CVE-2026-47131

vm2: Sandbox Escape

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, by combining Buffer.call.call({}.lookupGetter, Buffer, "proto"), Buffer.call.call({}.lookupSetter, Buffer, "proto"), and Node.js's ERRINVALIDARG_TYPE Error, the host's TypeError constructor can be obtained, which allows the escape from the sandbox. This allows attackers to run arbitrary code. This issue has been patched in version 3.11.4.
