This vulnerability exposes a critical gap in Node.js sandboxing mechanisms where unchecked type conversions in native C++ bindings allow untrusted code to escape isolation boundaries and hijack host execution. While the core V8 isolation primitives remain intact, the flaw in data transfer logic undermines the security guarantees of isolated-vm versions prior to 7.0.1 and 6.2.0, necessitating immediate patching for applications relying on secure JavaScript environments.
Critical isolated-vm Flaw Lets Untrusted JavaScript Escape Sandbox and Hijack Host Execution
A critical security flaw in the popular Node.js sandboxing library isolated-vm could allow untrusted JavaScript to escape its V8 sandbox and potentially hijack execution in the host process. The issue, tracked as GHSA-864f-rcv7-6rh4 and awaiting a CVE identifier, affects isolated-vm versions earlier than 7.0.1 and 6.2.0. The maintainers released fixes on August 8, 2026.
