CVE-2025-57847

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.

What this means for your business

It affects Redhat Ansible Automation Platform. It matters if your company, or a supplier that handles your data, runs it.
An attacker can use it only with access to the machine itself, with an administrator login, and without anyone at your company clicking anything.

What to do

1Check whether your company or your suppliers run Redhat Ansible Automation Platform, and which version. The affected versions are listed further down this page.
2If you do, apply the vendor's fix. A patch or vendor advisory has been published.
