Overview
Affected versions of this package are vulnerable to Improper Check for Dropped Privileges due to the improper handling of the unlinkat and funlinkat system calls when the AT_RESOLVE_BENEATH flag is used. An attacker can bypass directory containment by deleting files outside the intended directory tree by exploiting the failure to enforce path resolution restrictions.
