Remote Code Execution (RCE)

SandboxJS is vulnerable to Remote Code Execution RCE. The vulnerability is due to missing isolation and replacement of AsyncFunction and related function constructors, which allows an attacker to access the native host AsyncFunction via the .constructor property and execute arbitrary code outside...

Code Injection

Enclave is vulnerable to Code Injection. The vulnerability is due to exposure of a host-side Error object with an intact prototype chain to sandboxed code, which allows an attacker to traverse to the host Function constructor and execute arbitrary code in the Node.js host runtime...

enclave-vm Vulnerable to Sandbox Escape via Host Error Prototype Chain

A critical sandbox escape vulnerability exists in enclave-vm affected: 2.6.0, patched: 2.7.0 that can allow untrusted, sandboxed JavaScript to execute arbitrary code in the host Node.js runtime. When a tool invocation fails, enclave-vm exposes a host-side Error object to sandboxed code. This Erro...

CVE-2026-22686

Enclave is a secure JavaScript sandbox designed for safe AI agent code execution. Prior to 2.7.0, there is a critical sandbox escape vulnerability in enclave-vm that allows untrusted, sandboxed JavaScript code to execute arbitrary code in the host Node.js runtime. When a tool invocation fails,...

CVE-2026-22686 Sandbox Escape via Host Error Prototype Chain in enclave-vm

Enclave is a secure JavaScript sandbox designed for safe AI agent code execution. Prior to 2.7.0, there is a critical sandbox escape vulnerability in enclave-vm that allows untrusted, sandboxed JavaScript code to execute arbitrary code in the host Node.js runtime. When a tool invocation fails,...

CVE-2026-22686

The CVE-2026-22686 issue affects enclave-vm prior to version 2.7.0. A sandbox escape exists when a tool invocation fails and a host-side Error object is leaked into the sandbox, allowing traversal of the host realm prototype chain to reach the host Function constructor. This enables arbitrary cod...
