Vulnerability Title
vm2 3.9.6 before 3.11.7 Sandbox Bypass via Accessor Descriptor
Source: CVE Program / CVE List V5
Vulnerability 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.
