This issue stems from the /etc/passwd file being created with group-writable permissions during build time. 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 could allow the attacker to add a new user with any arbitrary UID, including UID 0, leading to full root privileges within the container."}], "lastModified": "2026-05-01T20:52:11.643", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:redhat:web_terminal:-:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "9D88B140-D2A1-4A0A-A2E9-1A3B50C295AD"}], "operator": "OR"}]}], "sourceIdentifier": "secalert@redhat.com"}
