CVE-2026-12382

Red Hat Ansible Automation Platform 2.6 VulnerabilityCVSS 8.2

A flaw was found in the AAP Gateway Envoy proxy configuration. The non-mTLS route to EDA event streams does not remove the Subject HTTP header from client requests, despite the source code defining requestHeadersToRemove for this header. An unauthenticated remote attacker can inject a spoofed Subject header matching a legitimate client certificate DN to bypass mTLS authentication and inject arbitrary events into protected EDA event streams.

No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.

Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.

Affected & fixed versions by distribution

Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.

No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
