Auth bypass in Red Hat Ansible Automation Platform 2
CVE-2026-76648
CopyAPIView (awx/awx/api/generics.py:873) sets permission_classes = (IsAuthenticated,), so DRF's get_object() performs no object-level RBAC. The get() handler (lines 988–991) explicitly guards with request.user.can_access(obj._class_, 'read', obj) — but post() (lines 1001–1010) does not. POST only checks: can_access(model, 'add', create_kwargs_check) can_access(model, 'copy_related', obj) For JobTemplate, can_add (awx/awx/main/access.py:1465–1520) gates on inventory.use_role + project.use_role + execution_environment.read_role — resource-level roles that do not imply read on the source JT — and can_copy_related (1522–1534) checks only credentials.use_role. None of these imply the caller can read the source JT.
