CVE-2026-26720Public exploitNetwork attack vector

Authenticated command execution via unsandboxed workflow functions

Published Mar 2, 2026 · Updated Mar 2, 2026

Code injection in Twenty CRM 1.15.0 and earlier allows remote authenticated users to execute arbitrary commands through serverless workflows. In self-hosted deployments, local.driver.ts transpiles workflow-supplied code with esbuild and loads it through Node.js require() in the main server process without isolation. Workflow-creation permission is required; successful exploitation runs with the Node.js service account and exposes host files, environment secrets, and shell-command execution.
