CVE-2026-92934 · vm2 before 3.11.8 Sandbox Escape RCE via AggregateError

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
