CVE-2025-57852 — MEDIUM (6.4)

Vulnerability Description

A container privilege escalation flaw was found in KServe ModelMesh container images. 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.
