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This advisory has been withdrawn because it is a duplicate of GHSA-633r-hq9m-c4ff.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.
