CVE-2026-84717 Red Hat — Exploit & Vulnerability Details MEDIUM

Parameter	Value
CVSS	5.3 (MEDIUM)
Type	CWE-204
Vendor	Red Hat
Public PoC	No

A flaw was found in the Ansible Automation Platform automation-controller. The unauthenticated Bitbucket Data Center webhook receiver skips HMAC signature verification for diagnostics:ping events after it has already looked up the target template, causing the endpoint to return HTTP 200 for a template that has a Bitbucket DC webhook configured and HTTP 403 otherwise. An unauthenticated remote attacker can use this response discrepancy as an oracle to enumerate which Job Template and Workflow Job Template IDs have Bitbucket DC webhooks configured, without knowing the secret webhook_key.
