## Overview

## Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-7q3f-wx44-378m. This link is maintained to preserve external references.

## Original Description
vm2 before 3.11.7 contains a module allowlist bypass vulnerability in isPathAllowedForModule that uses raw string prefix matching instead of boundary-anchored comparison. Attackers can reach non-allowlisted packages sharing a prefix with allowlisted modules by performing relative requires from allowlisted packages when transitive loading is disabled.

## Affected packages

- `vm2 <= 3.11.6`

## Remediation

Refer to the advisory for the patched release.
