Exploitation evidence

Disclosed: evidence found.
CVE published 23 Jun 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Red Hat has released an update for Red Hat Ansible Automation Platform 2.7 that addresses this vulnerability. Users should apply this update after ensuring all previously released errata relevant to their system have been applied. Until the update is applied, it is recommended to restrict network access to the EDA websocket endpoint and review and limit user accounts with any level of Ansible Automation Platform authentication to reduce exposure.

Description

Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to individual teams, while automation developers retain the freedom to write tasks that leverage existing knowledge without the overhead. Ansible Automation Platform makes it possible for users across an organization to share, vet, and manage automation content by means of a simple, powerful, and agentless language. For details about this release, refer to the release notes listed in the References section.

Impact

An authenticated attacker can exploit this vulnerability to obtain sensitive credentials in plaintext, including OAuth tokens, vault passwords, and SSH keys. This compromises confidentiality and integrity by exposing and potentially allowing modification of critical credentials. The vulnerability has a CVSS v3.1 base score of 9.6 (critical) as assessed by Red Hat, reflecting high impact on confidentiality and integrity with low attack complexity and no user interaction required. There is no known exploitation in the wild at this time.

Summary

CVE-2026-11807 is a missing authorization vulnerability in the Event-Driven Ansible (EDA) websocket API of Red Hat Ansible Automation Platform. Specifically, the /api/eda/ws/ansible-rulebook endpoint fails to verify user permissions when handling Worker messages. This flaw allows any authenticated user to forge messages with arbitrary activation_id values to retrieve sensitive plaintext credentials associated with those activations, such as OAuth tokens, vault passwords, and SSH keys. The vulnerability affects versions 2.6 through 2.7 of the platform. Red Hat has issued a security advisory (RHSA-2026:28440) with updated container images and recommends applying the update after ensuring all previous errata are applied. Mitigations include restricting network access to the EDA websocket endpoint and limiting user accounts with Ansible Automation Platform authentication until the fix is applied.

Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #4OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
