Technical 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.

——5StringListPathField.to_internal_value() calls os.path.exists() on unbounded user-supplied paths. 200 vs 400 response reveals existence of arbitrary absolute paths on the controller-web pod. Tenant superuser can confirm /etc/tower/SECRET_KEY, k8s service-account token, receptor sockets, ConfigMap mount points. Mainly impactful on managed AAP (ansiblecloud.com) where tenant admin != host admin.2d CVE-2026-714585.0 MED

——6URLModificationMiddleware resolves named-URL lookups against unfiltered Model.objects before RBAC. The 403→404 shim only rewrites 403 responses, leaving the pk=0 miss path with a different 404 detail string. Differential "Not found." vs "No <Model> matches..." reveals whether a named resource (org, credential, inventory, host) exists anywhere on the platform. Enables cross-tenant internal hostname enumeration.2d CVE-2026-891735.3 MED
