Bypass Vulnerabilities in Enclave-VM Enable Sandbox Escape

Publication date: 2026-02-06

Last updated on: 2026-02-20

Assigner: GitHub, Inc.

Description

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.

Attack-Flow Graph

Executive Summary

This vulnerability affects Enclave, a secure JavaScript sandbox used for safe AI agent code execution. Before version 2.10.1, the security measures in enclave-vm were insufficient. Specifically, the AST sanitization could be bypassed using dynamic property accesses, error object hardening did not fully address the vm module's unique behavior, and attempts to prevent function constructor access could be circumvented by exploiting host object references. These weaknesses allowed potential security bypasses within the sandbox environment.

Impact Analysis

This vulnerability could allow attackers to bypass the security restrictions of the Enclave JavaScript sandbox. As a result, malicious code might execute in ways that were intended to be prevented, potentially leading to unauthorized code execution or compromise of the sandbox environment's integrity.
