What happened
Collection of PortSwigger Research posts (2024–2026) summarizing high-impact web security research and tooling. Notable findings include parser-level SAML authentication bypasses (Ruby and PHP), chained namespace/round‑trip SAML attacks leading to unauthenticated admin access on GitLab, cookie-prefix and HttpOnly bypass techniques, practical HTTP desync/request-smuggling exploitation (including TRACE-based techniques), URL validation/SSRF bypasses, cache exploitation, CSS-based data exfiltration, timing oracles, JWT forging tooling (SignSaboteur), and improved WebSocket and manual-testing tool
