Enclave is a secure JavaScript sandbox designed for safe AI agent code execution. Prior to 2.10.1, the existing layers of security in enclave-vm are insufficient: The AST sanitization can be bypassed with dynamic property accesses, the hardening of the error objects does not cover the peculiar behavior or the vm module and the function constructor access prevention can be side-stepped by leveraging host object references. This vulnerability is fixed in 2.10.1.

Sandbox escape via infinite recursion and error objects

CVE-2026-25533 [MEDIUM] CWE-835 Sandbox escape via infinite recursion and error objects
Sandbox escape via infinite recursion and error objects
**Note:** The npm package has moved to `@enclave-vm/core` (formerly `enclave-vm`).
All fixed versions and guidance refer to `@enclave-vm/core`.
### Summary
The existing layers of security in enclave-vm are insufficient: The AST sanitization can be bypassed with dynamic property accesses, the hardening of the error objects does not cover the peculiar behavior or the vm module and the function constructor access prevention can be side-stepped by leveraging host object references.
### Details
There is a bug in Node.js (https://www.staicu.org/publications/usenixSec2023-SandDriller.pdf) that makes the vm module leak host references inside the vm module in case of infinite recursion. An attacker can exploit these to escape the sandbox.
