Overview

Affected versions of this package are vulnerable to Improper Protection of Alternate Path through manipulation of nested archive structures. An attacker can bypass the security warning mechanism that prompts users when opening files marked with the 'Mark of the Web' (MotW). This bypass occurs because the 'Zone.Identifier' stream, which labels files as potentially unsafe, does not propagate to files within nested archives.
