Detailsinfo

A vulnerability classified as critical has been found in patriksimek vm2 up to 3.11.3. This affects the function Promise.prototype.finally. The manipulation with an unknown input leads to a dynamically-managed code resources vulnerability. CWE is classifying the issue as CWE-913. The product does not properly restrict reading from or writing to dynamically-managed code resources such as variables, objects, classes, attributes, functions, or executable instructions or statements. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, a sandbox escape vulnerability in vm2 allows arbitrary code execution in the host process when untrusted code is executed with async support on runtimes exposing WebAssembly JSPI (WebAssembly.promising / WebAssembly.Suspending). In the tested configuration, a JSPI-backed Promise can reach Promise.prototype.finally() in a way that bypasses the expected Promise-species hardening and exposes a host-originated rejection object to attacker-controlled species logic, breaking the sandbox boundary. This issue has been patched in version 3.11.4.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-47210 since 05/19/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

Upgrading to version 3.11.4 eliminates this vulnerability.
