This critical-severity CVE scores 10.0 under NVD CVSS v3. EPSS exploit probability: 1.2%, top 34% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

vm2 is an open source vm/sandbox for Node.js. In vm2 prior to version 3.10.2, Promise.prototype.then Promise.prototype.catch callback sanitization can be bypassed. This allows attackers to escape the sandbox and run arbitrary code. In lib/setup-sandbox.js, the callback function of localPromise.prototype.then is sanitized, but globalPromise.prototype.then is not sanitized. The return value of async functions is globalPromise object. Version 3.10.2 fixes the issue.
