What happened
Collection of PortSwigger Research posts (2023–2026) covering numerous high-impact web security discoveries and tools. Key technical findings include parser-level SAML inconsistencies enabling full authentication bypasses in Ruby/PHP SAML ecosystems (including chained namespace confusion/round‑trip attacks against GitLab), widespread HTTP/1.1 desync/request‑smuggling classes that can enable site takeover, new desync exploitation techniques (TRACE), cookie parser and prefix bypasses (including __Host / __Secure and phantom $Version cookie exploits), HttpOnly cookie‑theft methods, CSS‑based data
