CVE-2026-57138Public exploitNetwork attack vectorHinoki check available

Host code execution via Function constructor escape

Published Sep 15, 2026 · Updated Sep 15, 2026

Sandbox escape in PraisonAI 1.4.0 through 1.7.1 allows remote authenticated users to execute code in the host Node.js process. The codeMode tool passes untrusted JavaScript to new Function inside with(sandbox), while a denylist and shadowed globals leave object constructors able to recover the real Function. Control of codeMode input is required; escaped code inherits the Node.js process privileges and can read secrets, modify files, spawn commands, or stop the process.
