AI-suggested

No effective mitigation is currently available that meets Red Hat Product Security criteria for ease of use, deployment, and stability. Users should monitor Red Hat advisories for updates. The correct fix involves code changes to make the diagnostics:ping response independent of template existence or require signature verification for ping events.

Description

CVE-2026-84717 is an information disclosure vulnerability in Red Hat Ansible Automation Platform 2.5 for RHEL 8. The flaw exists in the automation-controller's Bitbucket Data Center webhook receiver, where unauthenticated diagnostics:ping events skip HMAC signature verification after template lookup. This causes the endpoint to respond with HTTP 200 if a Bitbucket DC webhook is configured on a template and HTTP 403 otherwise. An unauthenticated attacker can use this response difference to enumerate which Job Template and Workflow Job Template IDs have Bitbucket DC webhooks configured without knowing the secret webhook key.
