Overview
Affected versions of this package are vulnerable to Time-of-check Time-of-use (TOCTOU) Race Condition in the cp process. An attacker can access sensitive file contents by exploiting a race condition where a symbolic link is swapped in place of a regular file between the time the file is checked and when it is opened, allowing the contents of arbitrary files to be copied to a location controlled by the attacker. This is only exploitable if the attacker has concurrent write access to the source path.
