Affected versions of this package are vulnerable to Time-of-check Time-of-use (TOCTOU) Race Condition via the gateway.py component, when a file is first written and then its permissions are later changed using chmod. An attacker can exploit the time window between when the file is initially written and when its permissions are modified and may gain access to the file.
