## Overview

## Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-c48m-32m9-vx93. This link is maintained to preserve external references.

## Original Description
vm2 before 3.11.7 contains an incorrect authorization vulnerability in the external package allowlist check that uses non-exact substring matching instead of full package-name boundary validation. Attackers can bypass the allowlist by requiring a colliding package name that contains an allowlisted package substring, causing vm2 to load and execute unauthorized host packages in the host context.

## Affected packages

- `vm2 <= 3.11.6`

## Remediation

Refer to the advisory for the patched release.
