CVE-2026-24781 is a critical sandbox escape vulnerability in vm2, the Node.js VM/sandbox library. The flaw affects vm2 versions prior to 3.11.0 and is triggered through the inspect function. The vulnerability arises from inspect-related behavior that can unwrap proxies and expose raw host-side objects or vm2 internal proxy-handling state, undermining vm2’s proxy-based isolation boundary. Reported exploit paths indicate that an attacker able to execute JavaScript inside a vm2 instance can leverage this exposure to bypass the sandbox bridge, recover access to host-realm functionality, and ultimately execute arbitrary commands on the underlying host system. The issue was fixed in vm2 3.11.0.
