SCA: security update for enclave-vm (GHSA-7qm7-455j-5p63)
critical Tenable Self-Hosted Container Security Plugin ID 436761
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- 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, enclave-vm exposes a
host-side Error object to sandboxed code. This Error object retains its host realm prototype chain, which
can be traversed to reach the host Function constructor. An attacker can intentionally trigger a host
error, then climb the prototype chain. Using the host Function constructor, arbitrary JavaScript can be
compiled and executed in the host context, fully bypassing the sandbox and granting access to sensitive
resources such as process.env, filesystem, and network. This breaks enclave-vm’s core security guarantee
of isolating untrusted code. This vulnerability is fixed in 2.7.0. (CVE-2026-22686)
