Which versions of Praisonaiagents are affected by EUVD-2026-21513?

PraisonAIAgents versions before 1.5.128 contain an unauthenticated Server-Side Request Forgery vulnerability that allows attackers to redirect the application into crawling internal systems, cloud…. A patch is available.

How to fix or mitigate EUVD-2026-21513?

Within 24 hours: Inventory all PraisonAIAgents deployments and confirm current version (check requirements.txt or pip show praisonaiagents). Within 7 days: Upgrade all instances to version 1.5.128 or later; confirm Tavily API keys are configured in production to disable fallback crawlers, or deploy Crawl4AI as a validated alternative. Within 30 days: Implement network segmentation to restrict outbound HTTP/HTTPS from PraisonAI processes, add WAF/proxy rules to block requests to 169.254.169.254 and internal RFC1918 ranges, and conduct log review for suspicious URL patterns in agent inputs.

DescriptionGitHub Advisory

PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, web_crawl's httpx fallback path passes user-supplied URLs directly to httpx.AsyncClient.get() with follow_redirects=True and no host validation. An LLM agent tricked into crawling an internal URL can reach cloud metadata endpoints (169.254.169.254), internal services, and localhost. The response content is returned to the agent and may appear in output visible to the attacker. This fallback is the default crawl path on a fresh PraisonAI installation (no Tavily key, no Crawl4AI installed). This vulnerability is fixed in 1.5.128.

AnalysisAI

Server-Side Request Forgery (SSRF) in PraisonAIAgents versions prior to 1.5.128 allows unauthenticated attackers to manipulate LLM agents into crawling arbitrary internal URLs. The httpx fallback crawler accepts user-supplied URLs without host validation and follows redirects, enabling access to cloud metadata endpoints (169.254.169.254), internal services, and localhost. …
