Overview

Affected versions of this package are vulnerable to Time-of-check Time-of-use (TOCTOU) Race Condition due to the lack of proper protection in the safe_traversal process. An attacker can manipulate directory traversal operations by exploiting symlink race conditions between the time a file or directory is checked and the time it is used.
