Google's Angular team has released two security patches addressing SSR vulnerabilities. The first, rated critical, involves a server-side request forgery (SSRF) and header injection flaw where Angular's URL reconstruction logic blindly trusts user-controlled HTTP headers like Host and X-Forwarded-*, enabling attackers to steal Authorization headers, session cookies, or access internal services. The second, rated moderate, is an open redirect via the X-Forwarded-Prefix header that can enable phishing and SEO hijacking. Developers are urged to update SSR apps immediately. Those unable to update should avoid using req.headers for URL construction and implement middleware to validate hostnames and ports.
