Description
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-633r-hq9m-c4ff. This link is maintained to preserve external references.
Original Description
vm2 versions from 3.9.6 before 3.11.7 fail to properly restrict access to accessor properties on frozen objects, allowing sandboxed scripts to bypass vm.freeze() and vm.readonly() protections. Attackers can use Object.getOwnPropertyDescriptor() or lookupSetter() to extract and invoke host object setters directly, mutating properties the embedder explicitly marked read-only.
Affected versions

| Package | Vulnerable | Fixed in |

How to fix
No fixed version has been published yet. Until one is, remove or replace the package, or turn off or isolate the affected feature. This page updates when a fix ships.

Weakness
CWE-471: Modification of Assumed-Immutable Data (MAID)
The product does not properly protect an assumed-immutable element from being modified by an attacker.
How to prevent it
- Architecture and Design, Operation, Implementation: When the data is stored or transmitted through untrusted sources that could modify the data, implement integrity checks to detect unauthorized modification, or store/transmit the data in a trusted location that is free from external influence.
