What happened

Collection of PortSwigger Research publications (2024–2026) summarizing numerous modern web-exploitation techniques and tooling. Highlights include parser-level SAML inconsistencies that enable full authentication bypasses (Ruby/PHP SAML ecosystems, chained namespace/attribute attacks leading to unauthenticated admin access on affected deployments), pervasive HTTP desynchronisation (HTTP/1.1 desync/request smuggling) exploitation techniques and new TRACE-based desync primitives, cookie-prefix and HttpOnly bypass techniques, CSS-based data-exfiltration methods, JWT/signed-token forging tooling,
