EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 3.9%, top 11% 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).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

There exists a vulnerability in source code transformer (exception sanitization logic) of vm2 for versions up to 3.9.15, allowing attackers to bypass handleException() and leak unsanitized host exceptions which can be used to escape the sandbox and run arbitrary code in host context. A threat actor can bypass the sandbox protections to gain remote code execution rights on the host running the sandbox. This vulnerability was patched in the release of version 3.9.16 of vm2.
