Name of the Vulnerable Software and Affected Versions:

mmaitre314 picklescan versions through 0.0.30

Description:

A protection mechanism failure in picklescan allows a remote attacker to bypass the unsafe globals check. The scanner performs an exact match for module names, enabling malicious payloads to be loaded via submodules of dangerous packages, such as `asyncio.unix events` instead of `asyncio`. Loading an incorrectly considered safe file after the scan can lead to the execution of malicious code.

Recommendations:

Update picklescan to a version beyond 0.0.30.
