| Doc Text: |
A flaw was found in vm2, an open-source virtual machine (VM) sandbox for Node.js. This sandbox escape vulnerability allows an attacker to execute arbitrary code in the host process. This occurs when untrusted code is executed with asynchronous (async) support on runtimes that expose WebAssembly JavaScript Promise Integration (JSPI). Specifically, a JSPI-backed Promise can bypass expected Promise-species hardening, exposing a host-originated rejection object to attacker-controlled logic and breaking the sandbox boundary.
