A flaw was found in vm2 (before 3.11.3). Host exceptions can be caught from sandbox code using yield* inside an async generator; closing the generator with return() awaits the value and passes host exceptions back into the sandbox iterator, enabling escape and arbitrary host command execution. Fixed in 3.11.3. vm2: vm2: Arbitrary Code Execution due to sandbox escape vulnerability vm2 is vulnerable to sandbox escape via async generator yield* exception handling that delivers host exceptions into sandbox control flow. A remote unauthenticated attacker who can submit sandboxed async generator code may escape the sandbox and execute arbitrary commands.
