Vulnerability from cvelistv5 – Published: 2026-04-03 22:54 – Updated: 2026-04-06 13:23

Title

PraisonAI: SSRF in FileTools.download_file() via Unvalidated URL

Summary

PraisonAI is a multi-agent teams system. Prior to version 1.5.95, FileTools.download_file() in praisonaiagents validates the destination path but performs no validation on the url parameter, passing it directly to httpx.stream() with follow_redirects=True. An attacker who controls the URL can reach any host accessible from the server including cloud metadata services and internal network services. This issue has been patched in version 1.5.95.

Severity

8.6 (High)
