CVE-2025-34267Public exploitNetwork attack vectorHinoki check available

Authenticated code execution via browser binary overrides

Published Oct 14, 2025 · Updated Oct 14, 2025

Command injection in Flowise 3.0.1 through 3.0.8 allows remote authenticated users to execute arbitrary code through custom tools. The nodevm tool harness exposes Puppeteer and Playwright launch options, so executablePath and arguments start attacker-chosen host programs outside the sandbox. The attacker needs credentials and permission to create or run a tool; later releases remain exposed only when ALLOW_BUILTIN_DEP is enabled.
