What happened
Collection of PortSwigger Research posts (2024–2026) highlighting multiple high-impact web-security findings and tooling updates. Notable technical discoveries include parser-level SAML inconsistencies that enable full authentication bypasses (Ruby/PHP and chained attacks against GitLab), a renewed analysis of HTTP/1.1 desynchronisation (“desync”) vulnerabilities and new TRACE-based exploitation techniques, cookie-prefix and HttpOnly bypasses enabling session theft, CSS-based data exfiltration techniques, JWT forgery tooling (SignSaboteur), and numerous request-smuggling, cache-poisoning, and
