Internal service disclosure via unchecked redirect targets
Published Sep 14, 2026 · Updated Sep 14, 2026
SSRF in SpiderTools in PraisonAI before 4.6.59 allows attackers to read internal HTTP responses through crafted redirects. SpiderTools.scrape_page validates only the initial URL, then requests.Session.get follows an unvalidated Location target and returns the destination response body. Exploitation requires influence over a URL passed to a SpiderTools caller; disclosure is limited to HTTP services reachable from the host.
