What happened
A PortSwigger Research collection (2024–2026) cataloguing novel web attack techniques, exploit primitives and tooling. Key high-impact findings include parser/namespace inconsistencies that enable full SAML authentication bypasses (Ruby/PHP ecosystems — unauthenticated admin access on GitLab demonstrated), widespread HTTP/1.1 desynchronisation and request-smuggling/desync exploitation (including TRACE-based exploitation), cookie-prefix and HttpOnly bypass techniques, cache/URL-validation/SSRF abuses, CSS-based data exfiltration, JWT signing forgery tooling (SignSaboteur), WebSocket blind spots
