Container root escalation via group-writable passwd file
Published Apr 8, 2026 · Updated Aug 27, 2026
Privilege escalation in certain Red Hat Ansible Automation Platform container images allows local users to gain root access within a container. The image build creates /etc/passwd with group-write permission, letting a non-root process in group 0 append an account with UID 0. Command execution inside an affected container and root-group membership are required; the resulting privilege is confined to that container.
