GHSA-4xmw-hh9q-4q7c

Duplicate Advisory: vm2 sandbox escape to host RCE via revisited host-wrapped AggregateError bypassing Error sanitization cycle short-circuit

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-x965-fc75-jpqh. This link is maintained to preserve external references.

Original Description

vm2 before 3.11.8 contains an incomplete fix for Error.cause sanitization that allows sandbox escape when revisited host-wrapped AggregateError objects are caught within a single exception handler traversal. Attackers can exploit cycle detection bypass in handleException to access unsanitized host proxies embedded in the errors array, enabling full remote code execution and process information disclosure from the sandbox.
