Description

A container privilege escalation flaw was found in certain Ansible Automation Platform images. This issue arises from the /etc/passwd file being created with group-writable permissions during the build process. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, can leverage their membership in the root group to modify the /etc/passwd file. This vulnerability allows an attacker to add a new user with any arbitrary UID, including UID 0, gaining full root privileges within the container.
