Technical details

The vulnerability exists in the POST endpoint `/api/function/execute` in the route.ts file, where the `code` parameter from the request body is directly embedded into a Node.js Script context without sanitization, validation, or filtering (CWE-74, CWE-94). The vulnerable code concatenates user-supplied input into a JavaScript string that is then executed via the `script.runInContext()` method. The attack is network-accessible and requires no authentication; an attacker can craft a POST request with malicious JavaScript code in the `code` parameter to execute arbitrary Node.js code, including spawning child processes and executing system commands. A proof-of-concept demonstrates executing arbitrary shell commands with full process privileges. The vulnerability was patched in pull request #1149.
