CVE-2026-84717: Red Hat Ansible Automation Platform automation-controller webhook signature verification bypass

CVE-2026-84717 · Severity: medium · CVSS 5.3 · Published 2026-09-23

A flaw in Red Hat Ansible Automation Platform's webhook receiver allows unauthenticated attackers to enumerate which job templates have Bitbucket webhooks configured. By sending specially crafted requests, an attacker can determine which templates are webhook-enabled based on the HTTP response code, potentially exposing infrastructure configuration without authentication. This information disclosure could facilitate targeted attacks against job automation workflows.

Technical details

The Bitbucket Data Center webhook receiver in automation-controller skips HMAC signature verification for diagnostics:ping events after resolving the target template, allowing response code differences (HTTP 200 vs 403) to leak template configuration. The vulnerability is unauthenticated and requires only network access to the webhook endpoint. An attacker can enumerate Job Template and Workflow Job Template IDs with active Bitbucket webhooks without knowledge of the webhook_key secret.
