What is CVE-2026-11807?

A vulnerability in the Event-Driven Ansible (EDA) websocket API allows authenticated users to exploit the /api/eda/ws/ansible-rulebook endpoint. This issue occurs due to a lack of user permission verification when processing Worker messages. As a result, an attacker can send forged messages containing arbitrary activation_ids, which may allow the retrieval of sensitive plaintext credentials including OAuth tokens, vault passwords, and SSH keys.
