## Overview

## Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-9m3x-qqw2-h32h. This link is maintained to preserve external references.

## Original Description
picklescan before 1.0.1 contains an unsafe deserialization vulnerability allowing unauthenticated users to execute arbitrary code by hiding eval calls nested under callable objects via getattr. Attackers can embed malicious code in pickle files that evades detection but executes when the pickle is loaded from untrusted sources.

## Affected packages

- `picklescan < 1.0.1`

## Remediation

Refer to the advisory for the patched release.
