Internal resource disclosure via unchecked redirects
Published Aug 25, 2026 · Updated Aug 25, 2026
SSRF in Mervin Praison PraisonAI before 4.6.58 and praisonaiagents before 1.6.58 allows attackers to read internal resources. The web_crawl path validates only the initial URL, while _crawl_with_httpx follows redirects without rechecking each destination against private, loopback, or link-local ranges. An attacker must influence a registered crawl target through a task or prior-page prompt injection; the default httpx provider returns cloud metadata or internal-service content to the agent context.
