A local authenticated user with control over a target account's home directory can exploit a privileged symlink dereference vulnerability in the `ssh-add-public-key.sh` helper. When this helper runs with elevated privileges, it can be tricked into following attacker-controlled symlinks within the `.ssh` or `authorized_keys` paths. This allows the attacker to arbitrarily change file ownership and modes, potentially leading to local privilege escalation and impacting the integrity, confidentiality, and availability of the system.","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-91151"},{"at":"2026-11-11T21:33:00.000Z","source":"C29","sourceName":"CIRCL Vulnerability-Lookup","role":"Database","severity":2,"title":"GHSA-7vqx-f59g-6xhv / CVE-2026-91151","text":"A flaw was found in Cockpit.
