What happened

Collection of PortSwigger Research posts (Top 10 Web Hacking Techniques 2025 and related publications) summarizing numerous high-impact web-security findings and tooling from 2023–2025. Notable technical highlights include parser-level SAML authentication bypasses (Ruby/PHP) enabling unauthenticated admin access on affected deployments, multiple HTTP desynchronisation/desync and request-smuggling exploitation techniques (including TRACE-based exploitation and HTTP/1.1 desync analysis), cookie-parser discrepancies enabling bypasses of __Host/__Secure prefixes and HttpOnly protections (cookie-s‎
