What happened

Collection of PortSwigger Research posts (2024–2026) detailing multiple high-impact web security findings and tooling: parser-level SAML authentication bypasses (including ruby-saml chains leading to unauthenticated admin access on GitLab), large-scale HTTP desynchronisation/request-smuggling techniques (including TRACE-assisted exploitation and an “HTTP/1.1 desync endgame”), cookie-prefix and HttpOnly bypasses (cookie-sandwich / phantom $Version attacks), CSS/inline-style exfiltration techniques, JWT forging tooling (SignSaboteur), WebSocket-focused fuzzing/exploitation, cache and URL‑parsing
