CVE-2026-91151Cockpit: cockpit: local privilege escalation via insecure symlink handling in public key addition helper

Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Enterprise Linux 7; Red Hat Red Hat Enterprise Linux 8; Red Hat Red Hat Enterprise Linux 9 Yayım: (7 saat önce)

Açıklama

A flaw was found in Cockpit. 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.

Zayıflık türü (CWE): CWE-59
