CVE-2026-54371

A flaw was found in the `attr` package. This vulnerability allows a local attacker to perform a symlink traversal attack by replacing a pathname component with a symbolic link - either during directory hierarchy traversal by `getfattr` or during backup restoration by `setfattr`, which reads and resolves full pathnames from backup files. In both cases, when these utilities are executed by a privileged process over a path controlled by the attacker, this can lead to local privilege escalation.
