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.\n\n## Affected\n\n- `vm2 < 3.11.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `vm2 3.11.0`","depth":"twilight","depthScore":47,"depthScoreParts":{"impact":47.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
