What happened
Collection of PortSwigger Research (2024–2026) documenting multiple high-impact web security techniques and exploit primitives. Key, high-risk findings include parser-level SAML authentication bypasses (ruby-saml/php-saml) enabling unauthenticated admin access (e.g., GitLab Enterprise), widespread HTTP/1.1 desynchronisation (request smuggling/desync) that can lead to upstream takeover (including new TRACE-assisted exploitation), cookie-parser discrepancies that bypass __Host/__Secure prefixes and HttpOnly protections, techniques for stealing data via CSS/CSS conditionals, JWT forging tools (e.
