Exploiting dynamic rendering engines to take control of web apps

Dynamic rendering services such as Rendertron and Prerender run a headless browser server-side for crawlers, and the URL it fetches is attacker-controlled through a spoofed crawler User-Agent or an open redirect. That gives SSRF to cloud metadata, and chained render and screenshot calls exfiltrate the token, leading to takeover of the host application.
