CVE-2023-29199 is a critical-severity vulnerability rated 10/10 on the CVSS scale. 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. EPSS estimates a 3.85% chance of exploitation in the next 30 days.
