What happened
PortSwigger Research published its Top 10 Web Hacking Techniques of 2025 and an associated set of in-depth research posts describing multiple high-impact web attack techniques and tooling. Notable findings include parser-level SAML inconsistencies (attribute pollution, namespace confusion) enabling full authentication bypasses in Ruby and PHP SAML ecosystems and chained attacks resulting in unauthenticated admin takeover of GitLab Enterprise; widespread HTTP/1.1 desynchronisation (desync) and request-smuggling risks and new exploitation methods (e.g., TRACE-assisted desync); cookie-parser and–
