What happened
Collection of PortSwigger Research posts (2024–2026) summarizing many high-impact web security research topics and tooling. Notable findings include parser-level SAML inconsistencies that enable full authentication bypasses in Ruby/PHP SAML libraries; widespread HTTP/1.1 desynchronisation (desync) and request-smuggling risks (including a TRACE-assisted exploitation path); techniques to bypass cookie prefixes (__Host, __Secure) and to steal HttpOnly cookies (cookie-sandwich); CSS-based data exfiltration methods; WebSocket fuzzing/exploitation gaps; JWT/signing forgery tooling (SignSaboteur); a
