CVE-2026-62176

PraisonAI: Code Injection via f-string Interpolation in Deploy API Server Generation

Published Oct 7, 2026 CVSS 3.1 · 9.1 Critical EPSS < 1% KEV · Not listed
Description
PraisonAI is a multi-agent teams system. Prior to version 4.6.78, the `deploy/api.py` module generates Python server code by directly interpolating the `agents_file` parameter into an f-string that is then written to a file and executed via `subprocess.Popen()`. An attacker who controls the `agents_file` value (via CLI argument, configuration, or upstream API) can inject arbitrary Python code. Version 4.6.78 patches the issue.
