Overview
Affected versions of this package are vulnerable to Time-of-check Time-of-use (TOCTOU) Race Condition via the mv process. An attacker can overwrite arbitrary files by exploiting a race condition during cross-device move operations, where the destination path is removed and recreated, allowing the attacker to replace it with a symbolic link before the copy occurs. This enables redirection of the write operation to an unintended file.
