This Week’s Pattern: The Security Vendor Is the Attack Surface — and Non-Human Identity Is the Theft Vector.

Three converging threads defined this week. First, the security vendors themselves are now the attack surface. Cisco shipped an unauthenticated-to-root RCE in Identity Services Engine and had a root zero-day in Catalyst SD-WAN Manager added to CISA’s Known Exploited Vulnerabilities catalog with no patch available. Fortinet’s FortiSandbox — a product whose entire job is to detonate and analyze malware safely — is itself under an active exploit chain. Microsoft shipped its largest-ever Patch Tuesday at over 200 CVEs including a Defender elevation-of-privilege zero-day under active exploitation. The products enterprises buy to enforce identity, segment networks, and detonate malware are the ones being exploited.

Second, AI coding agents are being hijacked through their own tool inputs. The “Agentjacking” technique injects malicious markdown into Sentry error events, which Claude Code and Cursor then execute as legitimate instructions over MCP. An attacker needs only the target’s public Sentry DSN. Researchers found 2,388 organizations with injectable DSNs and achieved 85% exploitation success across more than 100 tested orgs. The AI agent treats its tool output as trusted instruction — the same trust-boundary failure that defines this entire class of attack.

Third, non-human identity and OAuth tokens are now the dominant theft vector. Attackers abused a compromised Klue OAuth integration to run automated Python against the Salesforce REST API and exfiltrate CRM data — roughly a thousand queries in fifteen minutes. ServiceNow exposed instance data through an unauthenticated API endpoint. And SpyCloud’s 2026 report recaptured 18.1 million exposed API keys and tokens, with non-human identities now outnumbering humans 80-to-1. Behind those: SAP’s SAML signature-wrapping auth bypass at CVSS 9.9, a Joomla JCE flaw at the maximum CVSS 10.0, Chrome V8 and Arista EOS flaws added to KEV, and Novo Nordisk’s patient data breach. Twelve incidents. We built one of the best identity stacks out there — and we still tell every customer it’s the front door, not the whole house. Here are the ones that matter and what stops them.

Vendor Zero-Days & Active Exploitation

1 — Cisco ISE: Unauthenticated-to-Root RCE Reaches the OS and Escalates to Root

1 Cisco Identity Services Engine — Critical RCE Lets Unauthenticated Attackers Reach the OS and Escalate to Root VENDOR ADVISORY CRITICAL · VENDOR · RCE
SecurityWeek · June 17, 2026 · CVE-2026-20181 (CVSS 9.1) + CVE-2026-20190 · Cisco ISE

Cisco patched CVE-2026-20181, a CVSS 9.1 remote code execution flaw in Identity Services Engine caused by improper input validation, that lets an attacker reach the underlying operating system and escalate to root. A second flaw, the high-severity CVE-2026-20190, exposes hashed credentials to an unauthenticated attacker via information disclosure. Fixes landed in ISE 3.3 Patch 11 and 3.4 Patch 6 — but the fix for ISE 3.5 is not due until August 2026, leaving a multi-month exposure window for organizations on that release. Cisco ISE is the platform enterprises deploy specifically to make network access decisions — the system that decides who and what is allowed onto the network is itself unauthenticated-to-root.

An identity and access control platform with an unauthenticated path to root is the worst-case profile for a security product: the system that issues and enforces access decisions for the entire network can be taken over without credentials. The staggered patch schedule makes it worse — organizations on ISE 3.5 have a confirmed-severe vulnerability and no fix until August. When the identity enforcement plane is the attack surface, everything downstream of it inherits the compromise.

The product that decides who gets on the network should not be the thing that lets attackers on. RuntimeAI’s enforcement operates at the workload and data layer — so a compromised access appliance is the start of an investigation, not the end of your defense.

2 — Cisco Catalyst SD-WAN Manager: Root RCE Added to CISA KEV With No Patch Available

2 Cisco Catalyst SD-WAN Manager — Actively-Exploited Root RCE (CVE-2026-20245) Added to CISA KEV With No Patch VENDOR ADVISORY CRITICAL · VENDOR · KEV ZERO-DAY
The Hacker News · Week of June 11, 2026 · CVE-2026-20245 (CVSS 7.8) · Catalyst SD-WAN Manager · Federal deadline June 23

CISA added CVE-2026-20245, a CVSS 7.8 vulnerability in Cisco Catalyst SD-WAN Manager, to its Known Exploited Vulnerabilities catalog. An authenticated attacker can run arbitrary commands as root by submitting a crafted file to the management plane. The flaw is under active exploitation, and at the time of the KEV listing there was no patch available — a root zero-day in the network management plane with federal agencies given a remediation deadline of June 23. Catalyst SD-WAN Manager is the central control plane for software-defined wide-area networks; root on the manager is root on the network fabric’s brain.

The CISA KEV catalog is not a warning list — it is a confirmed-exploitation list. A root RCE in a network management plane with no available patch means every affected organization has an actively-exploited vulnerability and no vendor remedy to deploy. When the network management plane itself is a zero-day with no patch, the only available control is one that limits what a compromised manager can actually reach.

Most Advanced AI Security Zero Trust · Defence in Depth

A no-patch root zero-day in the network’s control plane has only one defense: limit what the compromised plane can reach. RuntimeAI’s workload-layer enforcement is that limit.

3 — Fortinet FortiSandbox: Exploit Chain Under Active Attack From 11 IPs Across 9 Countries

3 Fortinet FortiSandbox — Three-Bug Exploit Chain Yields Auth Bypass, Privilege Escalation, and Command Execution VENDOR ADVISORY HIGH · VENDOR · ACTIVE EXPLOITATION
CyberScoop · June 15, 2026 · CVE-2026-39808 + CVE-2026-39813 + CVE-2026-25089 · Fortinet FortiSandbox

Fortinet’s FortiSandbox is under an active exploit chain. CVE-2026-39808, an OS command injection flaw, has been exploited since June 9. CVE-2026-39813, a path traversal vulnerability, had its exploitation confirmed June 15. CVE-2026-25089 was patched June 9. Researchers tracked 49 exploitation events from 11 IP addresses across 9 countries in just six days; chained together, the bugs yield authentication bypass, privilege escalation, and arbitrary command execution. FortiSandbox exists to detonate and analyze suspicious files in isolation — the product whose purpose is to safely contain malware is itself being weaponized.

A malware-analysis appliance under active exploitation is a particularly dangerous compromise: it is a system that, by design, ingests and executes untrusted files, often holds broad visibility into the network’s threat telemetry, and is trusted by downstream security tooling. The multi-bug chain — auth bypass to privesc to command execution — and the geographic spread of attackers in six days indicate a coordinated campaign, not opportunistic scanning. The tool you bought to safely contain malware should not be the tool that gives attackers a foothold.

Most Advanced AI Security How RuntimeAI Stops This

Security appliances are privileged, broadly-trusted systems. RuntimeAI treats them as exactly that — baselined, egress-constrained, and audited — so a single appliance compromise does not become network-wide access.

4 — Microsoft June 2026 Patch Tuesday: Record 200+ CVEs and a Defender Zero-Day Under Active Exploitation

4 Microsoft Patch Tuesday — Largest-Ever Release Fixes 200+ Flaws Including a Microsoft Defender EoP Zero-Day VENDOR ADVISORY HIGH · VENDOR · ZERO-DAY
BleepingComputer · June 10–11, 2026 · CVE-2026-41091 + CVE-2026-45586 + CVE-2026-49160 · Microsoft Patch Tuesday

Microsoft shipped its largest-ever Patch Tuesday in June 2026: more than 200 vulnerabilities, 33 of them rated Critical, and multiple zero-days. CVE-2026-41091, a CVSS 7.8 elevation-of-privilege flaw in Microsoft Defender, is under active exploitation — the endpoint security product itself being used to escalate privileges. Two additional zero-days were publicly disclosed: CVE-2026-45586, a CTFMON elevation-of-privilege bug, and CVE-2026-49160, an HTTP.sys denial-of-service flaw. The sheer volume — 200-plus CVEs in a single cycle — guarantees that most enterprises cannot test and deploy every fix before attackers weaponize the highest-value ones.

An actively-exploited elevation-of-privilege flaw in Microsoft Defender is the recurring theme of this week in miniature: the security control becomes the escalation path. And a 200-plus CVE Patch Tuesday is itself a structural problem — the patch volume now exceeds what most enterprise change-management cycles can absorb in the window before exploitation. When patch volume outruns patch velocity, “unpatched” is the steady state for some surface at all times.

Most Advanced AI Security Zero Trust · Defence in Depth

The patch gap is structural — 200 CVEs in one cycle proves it. RuntimeAI ensures that “unpatched” does not mean “unprotected.”

AI Agent Exploitation

5 — “Agentjacking”: Sentry Error Events Hijack Claude Code and Cursor via MCP

5 Agentjacking — Malicious Sentry Error Events Are Executed as Instructions by AI Coding Agents Over MCP CRITICAL · AI AGENT · PROMPT INJECTION
The Hacker News · June 12, 2026 · Tenet Security · Sentry MCP · Claude Code & Cursor

Tenet Security researchers demonstrated “Agentjacking”: injecting malicious markdown into Sentry error events that AI coding agents then execute as legitimate instructions when those events are surfaced through MCP. The attacker needs only the target’s public Sentry DSN to submit a poisoned error event. Researchers found 2,388 organizations with injectable DSNs and achieved an 85% exploitation success rate across more than 100 tested organizations, with both Claude Code and Cursor shown running attacker-supplied commands at full developer privilege. The error-monitoring data the agent reads to help debug is treated as trusted instruction input — the same trust-boundary failure at the heart of every prompt-injection attack, now reaching the agent through a routine observability tool.

This is the trust-boundary problem on agent tool inputs, made concrete at scale. An AI coding agent that pulls error events through MCP cannot tell the difference between “here is a stack trace to debug” and “here are instructions to run” — because both arrive through the same channel and the agent treats tool output as authoritative. With only a public DSN required and an 85% hit rate, this is not a theoretical edge case; it is a working repeatable attack against the dominant AI coding agents. An AI coding agent is a privileged process operating on attacker-influenceable tool inputs — the inputs are the attack surface, not the prompts.

Most Advanced AI Security How RuntimeAI Stops This

AI coding agents must distrust their own tool inputs. RuntimeAI enforces that boundary at runtime — observability data is analyzed, never executed.

Critical CVEs Under Active Exploitation

6 — SAP June Patch Day: SAML Signature-Wrapping Auth Bypass on NetWeaver (CVE-2026-44748)

6 SAP NetWeaver AS ABAP — XML Signature Wrapping Lets Attackers Forge Identity and Cross Trust Boundaries CRITICAL · AUTH BYPASS · IDENTITY
SOCRadar · June 9, 2026 · CVE-2026-44748 (CVSS 9.9) + CVE-2026-27671 (CVSS 9.8) · SAP NetWeaver AS ABAP

SAP’s June Patch Day addressed CVE-2026-44748, a CVSS 9.9 XML Signature Wrapping flaw in the SAML authentication of NetWeaver AS ABAP and the ABAP Platform. Because the system fails to properly validate SAML signatures, an attacker can forge identity assertions and cross trust boundaries — presenting a manipulated assertion that the system accepts as a legitimately-authenticated identity. SAP also patched CVE-2026-27671, a CVSS 9.8 unauthenticated and automatable kernel RFC buffer overflow. NetWeaver underpins core ERP for a large share of global enterprises; a SAML signature-wrapping bypass means an attacker can impersonate any identity the SAML flow would otherwise grant.

Signature-wrapping is an identity-layer failure: the authentication system accepts a forged assertion because it validates the wrong part of the signed document. This is precisely the failure mode where a strong identity stack is necessary but not sufficient — the assertion looks valid, so identity alone waves it through. If the only check is “is this assertion signed,” a signature-wrapping attack walks straight through the front door wearing someone else’s badge.

Most Advanced AI Security Why RuntimeAI Customers Are Protected

A strong identity stack is the front door — not the whole house. RuntimeAI assumes the assertion can be forged and enforces behaviour and scope on every session regardless.

7 — Joomla Content Editor (JCE): Max-Severity Unauthenticated RCE Added to CISA KEV

7 Joomla JCE — CVSS 10.0 Improper Access Control Lets Unauthenticated Attackers Upload and Run PHP CRITICAL · RCE · KEV
The Hacker News · June 16, 2026 · CVE-2026-48907 (CVSS 10.0) · Joomla Content Editor · Federal deadline June 19

CISA added CVE-2026-48907, a maximum-severity CVSS 10.0 improper access control flaw in the Joomla Content Editor (JCE) extension affecting versions 1.0.0 through 2.9.99.4, to its Known Exploited Vulnerabilities catalog. The flaw lets unauthenticated attackers upload and execute PHP by creating editor profiles — full remote code execution on public Joomla sites at low attack complexity. It is patched in version 2.9.99.5, with a federal remediation deadline of June 19. A perfect CVSS 10.0, no authentication required, and trivial exploitation against a widely-deployed CMS extension is a recipe for mass compromise.

A CVSS 10.0 unauthenticated RCE in a popular CMS extension is the classic mass-exploitation profile: low complexity, no credentials, and a large internet-facing install base. Public-facing web servers running the vulnerable JCE versions are reachable by anyone, and PHP upload-and-execute is a direct path to web shell and beyond. An internet-facing CMS that lets anonymous users upload and run code is not a vulnerability to schedule — it is one to remediate before the next scan finds it.

Most Advanced AI Security How RuntimeAI Stops This

A CVSS 10.0 unauthenticated RCE demands patching now — and a compensating control for the window before every site is patched. RuntimeAI provides both visibility and that window control.

8 — CISA Adds Chrome V8 and Arista EOS Flaws to KEV (CVE-2026-11645 + CVE-2026-7473)

8 CISA KEV Roundup — Chrome V8 Out-of-Bounds R/W and Arista EOS Packet-Decapsulation Flaw (No Patch Planned) VENDOR ADVISORY HIGH · KEV ROUNDUP · ACTIVE EXPLOITATION
The Hacker News · June 2026 · CVE-2026-11645 (CVSS 8.8) + CVE-2026-7473 (CVSS 6.9) · Chrome V8 & Arista EOS · Federal deadline June 23

CISA added two more vulnerabilities to its Known Exploited Vulnerabilities catalog. CVE-2026-11645 is a CVSS 8.8 out-of-bounds read/write in Chrome’s V8 JavaScript engine, allowing remote code execution via a malicious HTML page — a drive-by browser compromise. CVE-2026-7473 is a CVSS 6.9 packet-decapsulation flaw in Arista EOS, the network operating system, for which no patch is planned, meaning affected organizations have a permanent compensating-control problem rather than a patch-and-move-on fix. Both carry a federal remediation deadline of June 23. The pairing — a browser engine and a switch operating system — spans the full range from endpoint to network fabric.

The Chrome V8 flaw is a classic drive-by: a user visits a malicious page and gets code execution on the endpoint. The Arista EOS flaw is the harder problem — a KEV-listed vulnerability in core network infrastructure with no patch planned means the only path forward is a compensating control that limits exploitability indefinitely. When the vendor says “no patch,” the only defense left is one that does not depend on the vulnerability being fixed.

Most Advanced AI Security Zero Trust · Defence in Depth

“No patch planned” is the most dangerous line in any advisory. RuntimeAI’s workload- and egress-layer controls are the defense that works when patching is not an option.

Non-Human Identity & OAuth Abuse

9 — Klue OAuth Integration Abused to Steal Salesforce CRM Data via Automated Python

9 Klue / Salesforce — Compromised Service Account Mints OAuth Tokens to Exfiltrate CRM Data at Machine Speed HIGH · NHI / OAUTH · THIRD-PARTY RISK
ReliaQuest · Week of June 11, 2026 · Klue OAuth integration · Salesforce REST API · ShinyHunters / UNC6395 patterns

Attackers authenticated via a compromised Klue (competitive-intelligence app) service account, minted OAuth tokens, and ran automated Python against the Salesforce REST API to exfiltrate CRM data. They enumerated the Salesforce object catalog, executed roughly a thousand queries in a fifteen-minute window, and sustained extraction over about twenty-four hours before Salesforce disabled the Klue Battlecards integration. The activity patterns resemble ShinyHunters / UNC6395 campaigns. This is textbook non-human-identity and third-party OAuth token abuse: a connected app’s service account becomes the key to the customer’s entire CRM, governed by the third party’s security controls rather than the customer’s.

This is the dominant theft vector of the moment, demonstrated end to end. A third-party OAuth integration granted broad read access to Salesforce; compromise the integration’s service account and you inherit that access — no user credential, no MFA prompt, just a non-human identity minting tokens and querying the REST API at a pace no human operates at. The thousand-queries-in-fifteen-minutes signature is exactly what distinguishes machine identity abuse from human activity. Every connected app with a service account and an OAuth grant is a non-human identity that can read your CRM — governed by the vendor’s security, not yours.

Most Advanced AI Security Why RuntimeAI Customers Are Protected

Your connected apps hold non-human identities with keys to your CRM. RuntimeAI ensures those identities are inventoried, behaviourally enforced, and revocable — so a compromised integration cannot become a CRM-wide breach.

10 — ServiceNow: Unauthenticated API Endpoint Exposes Instance Data

10 ServiceNow — Unauthorized Access to Instance Data via an API Endpoint Lacking Proper Authentication HIGH · API SECURITY · DATA EXPOSURE
SOCRadar · June 9–10, 2026 · ServiceNow · /api/now/related_list_edit/create · Australia platform release and earlier

ServiceNow disclosed unauthorized access to instance data through an API endpoint — reportedly /api/now/related_list_edit/create — that lacked proper authentication. Suspicious activity was observed on June 2–3 and detected on June 5. The exposure affects customers on the Australia platform release and earlier releases with specific configurations; exact record counts have not been disclosed. ServiceNow holds some of the most sensitive operational data in the enterprise — IT service records, asset inventories, and workflow data — making an unauthenticated API path to instance data a serious exposure even before the full scope is known.

An unauthenticated API endpoint is the cleanest possible failure mode: no credential to steal, no token to abuse — the access control simply was not enforced on that path. As enterprises expose more functionality through APIs, the endpoints that quietly skip authentication become the breach. Every API endpoint is an access-control decision; the one that forgot to make it is the one that leaks.

Most Advanced AI Security Zero Trust · Defence in Depth

An endpoint that skips authentication is an access-control decision left unmade. RuntimeAI enforces access and egress at the data layer — so a single missing auth check does not become an open instance.

Data Breaches

11 — Novo Nordisk: Patient and Healthcare-Professional Data Breach Disclosed

11 Novo Nordisk — Pharma Giant Discloses Exposure of Patient and Healthcare-Professional Data HIGH · DATA BREACH · HEALTHCARE
Breach notice · June 11, 2026 · Novo Nordisk · Patient & healthcare-professional data

Novo Nordisk, one of the world’s largest pharmaceutical companies, disclosed a data breach exposing patient and healthcare-professional data. The company is notifying affected groups via tailored letters; the total number of individuals affected has not yet been disclosed. Patient and healthcare-professional data in the pharmaceutical context carries elevated sensitivity — it can tie individuals to specific conditions, treatments, and prescribing relationships, with long-term privacy and identity-theft consequences that extend well past the disclosure date.

Healthcare and pharmaceutical breaches expose data that cannot be rotated like a password: a person’s medical conditions, treatments, and provider relationships are permanent attributes. The undisclosed scope and the use of tailored notification letters suggest a varied population across patient and professional categories, each with different sensitivity and regulatory obligations. For patient data, the consequence is not inconvenience — it is permanent exposure of the most sensitive attributes a person has.

Most Advanced AI Security Why RuntimeAI Customers Are Protected

Patient data is permanent — it cannot be rotated after a breach. RuntimeAI enforces protection at the data layer, regardless of how the credential that reached the data was obtained.

Industry

12 — SpyCloud 2026 Identity Exposure Report: An Explosion of Non-Human Identity Theft

12 SpyCloud 2026 Report — 18.1 Million Exposed API Keys and Tokens, Non-Human Identities Outnumber Humans 80-to-1 HIGH · INDUSTRY TREND · NON-HUMAN IDENTITY
Cybersecurity Insiders · Week of June 11, 2026 · SpyCloud 2026 Identity Exposure Report · KPMG / CSA data

SpyCloud’s 2026 Identity Exposure Report recaptured 18.1 million exposed API keys and tokens during 2025 — spanning payment, cloud, developer, and AI platforms — plus 6.2 million credentials and authentication cookies tied specifically to AI tools. The report sits alongside KPMG’s 2026 finding that non-human identities now outnumber humans by roughly 80-to-1, and a Cloud Security Alliance figure that more than 16% of organizations do not track AI-identity creation at all. Taken together, the data describes a governance gap: machine identities are proliferating far faster than organizations can inventory, govern, or revoke them — and they are being stolen at scale.

This week’s individual incidents — the Klue OAuth abuse, the ServiceNow API exposure, the Agentjacking technique — are not isolated events; they are the SpyCloud data playing out in the field. 18.1 million stolen keys and an 80-to-1 ratio of machine to human identities mean the dominant identity on the network is no longer a person, and the dominant theft vector is no longer a password. If 16% of organizations cannot even see the AI identities they are creating, the question is not whether those identities will be abused — it is when, and whether anyone will notice.

Most Advanced AI Security Why RuntimeAI Customers Are Protected

Non-human identity is now the dominant identity on the network — and the dominant theft vector. We built one of the best identity stacks out there, and we still tell every customer it is the front door, not the whole house. RuntimeAI governs the machine identities most organizations cannot even see, and enforces behaviour and scope on every one of them.

🔍 This Week’s Through-Line: The Security Vendor Is the Attack Surface — and Non-Human Identity Is the Theft Vector

Cisco shipped an unauthenticated-to-root RCE in its identity platform and had a no-patch root zero-day in its SD-WAN management plane added to CISA KEV. Fortinet’s malware-analysis appliance is itself under an active exploit chain. Microsoft’s record 200-plus CVE Patch Tuesday includes a Defender elevation-of-privilege zero-day under active exploitation. The products enterprises buy to enforce identity, segment networks, and detonate malware are the ones being exploited — the security vendor is now the attack surface.

The Agentjacking technique shows AI coding agents being hijacked through their own tool inputs: a public Sentry DSN is enough to feed Claude Code and Cursor attacker instructions over MCP, with an 85% success rate. And the non-human-identity story dominates the rest — Klue’s OAuth integration minting tokens to drain Salesforce at a thousand queries in fifteen minutes, ServiceNow’s unauthenticated API endpoint, SAP’s SAML signature-wrapping bypass, and SpyCloud’s 18.1 million stolen API keys against an 80-to-1 ratio of machine to human identities. The pattern is not bad luck. It is the systematic exploitation of ungoverned machine identity and trusted-tool inputs.

RuntimeAI’s approach: inventory and govern every non-human identity with KYA and NHI Security; enforce a hard trust boundary on agent tool inputs with Coding Agent Defense and Flow Enforcer; scope and tokenize data access with PII Shield, the Secure LLM Router, and QuantumVault; and prove it all with the immutable Audit Black Box. We built one of the best identity stacks out there — and we still tell every customer it’s the front door, not the whole house. Twelve incidents. One pattern: the security vendor is the attack surface and non-human identity is the theft vector. Runtime governance is how you close both.
