CVE-2026-47686: Protection Mechanism Failure

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.6, handleException in lib/setup-sandbox.js sanitizes SuppressedError.error, SuppressedError.suppressed, and AggregateError.errors but does not sanitize Error.cause, allowing sandbox code to obtain a powerful host object such as process...
