AI Summary

A critical sandbox‑escape vulnerability in the isolated‑vm library, which runs JavaScript code in a separate process, was discovered and subsequently patched. The flaw could let attackers hijack the host’s control flow and potentially achieve remote code execution. Isolated‑vm, downloaded over a million times weekly, is incorporated into several open‑source AI agent automation frameworks such as n8n, Sim.ai, Mastra and Activepieces. The library’s purpose is to execute untrusted user‑provided JavaScript inside a V8‑based sandbox. The patch addresses the security risk for projects that rely on this component.
