CVE-2025-8766

Noobaa-core: excessive permissions of /etc could lead to escalation of privilege in the noobaa-core container

Published Mar 13, 2026 CVSS 3.1 · 6.4 Medium EPSS < 1% KEV · Not listed
Description
A container privilege escalation flaw was found in certain Multi-Cloud Object Gateway Core 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
