## What is CVE-2026-84717?

CVE-2026-84717 is a medium-severity vulnerability in Red Hat Ansible Automation Platform 2.5 for RHEL 8, published on 23 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

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.

Weakness: CWE-204 (Observable Response Discrepancy)

Affected product: Red Hat Ansible Automation Platform 2.5 for RHEL 8. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
