PraisonAI Has SSRF in FileTools.download_file() via Unvalidated URL
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
FileTools.downloadfile() in praisonaiagents validates the destination path but performs no validation on the url parameter, passing it directly to httpx.stream() with followredirects=True. An attacker who controls the URL can reach any host accessible from the server including cloud metadata services and internal network services.
Potential impact
On cloud infrastructure with IMDSv1 enabled, an attacker can retrieve IAM credentials via the EC2 metadata service and write them to disk for subsequent agent steps to exfiltrate. followredirects=True enables open-redirect chaining to bypass partial URL filters. Reachable via indirect prompt injection with no authentication required.
