What happened
Collection of PortSwigger Research posts (2023–2026) covering a wide range of modern, high-impact web attack techniques and tooling. Highlights include parser-level SAML authentication bypasses (Ruby/PHP) enabling unauthenticated admin access, HTTP/1.1 desynchronisation (request smuggling/desync) exploitation and mitigation failings, cookie-prefix and HttpOnly bypass techniques, CSS-based data exfiltration, JWT signing forgery tooling, and new exploitation techniques for WebSockets, caches, Unicode truncation, and timing oracles. The corpus also introduces offensive/defensive tooling and cheat
