CVE-2026-44001
HighWhat is CVE-2026-44001?
vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, a sandbox escape vulnerability in vm2 v3.10.5 allows any sandboxed code to crash the host Node.js process via a single Promise constructor that triggers an unhandled rejection propagating to the host. The fix for CVE-2026-22709 (v3.10.2) only sanitized the onRejected callback in .then() and .catch() overrides and did not address the executor-to-unhandledRejection path. This vulnerability is fixed in 3.11.0.
