2DescriptionCVE.org
PraisonAI versions before 1.6.78 contain a server-side request forgery vulnerability in the Crawl4AI/Chromium backend that allows attackers to bypass SSRF validation by exploiting DNS rebinding and HTTP redirects. Attackers can craft URLs that resolve to internal services after the initial validation check, enabling the headless browser to follow redirects and read internal responses including sensitive canary values.
AnalysisAI
Server-side request forgery in PraisonAI's Crawl4AI/Chromium crawling backend (all versions before 1.6.78) lets low-privileged users bypass URL allowlist/SSRF validation through DNS rebinding and HTTP redirects, causing the headless browser to reach internal-only services and return their responses. Because validation happens before the browser dereferences the URL, an attacker-controlled host can pass the check and then resolve or redirect to internal endpoints, exposing sensitive internal data (demonstrated with canary values). …
