What happened
Collection of PortSwigger Research posts (2024–2026) describing numerous practical and novel web-application attack techniques and tooling. Key highlights include parser-level SAML authentication bypasses (full auth bypasses in Ruby/PHP SAML stacks and chained attacks enabling unauthenticated admin access on GitLab), HTTP desynchronisation/request-smuggling research (including HTTP/1.1 desync ‘endgame’ and TRACE-assisted desync exploitation), cookie-prefix and HttpOnly cookie bypass techniques, CSS/inline-style exfiltration methods, WebSocket fuzzing/exploitation tooling, JWT forging tooling (
