What is CVE-2026-91202?

A vulnerability exists in Cockpit Files that permits a low-privileged local user to exploit directory symlinks. By crafting a directory with a symlink and utilizing the 'Paste as owner' feature, an attacker can change file ownership to unauthorized users. This alteration risks compromising data integrity and may lead to unauthorized read access if sensitive files are exposed. The exploitation of this vulnerability requires user participation in selecting a non-original file owner during paste operations, making it critical for users to understand potential risks.
