What happened

PortSwigger Research feed (2024–2026) aggregating high-impact web-security research and tools. Key themes include parser and protocol discrepancies (SAML namespace/attribute pollution enabling full auth bypasses in Ruby/PHP), HTTP desynchronisation/request-smuggling and an argument that HTTP/1.1 is inherently unsafe, cookie-parser attacks (bypassing __Host/__Secure prefixes and HttpOnly via 'cookie sandwich' and phantom $Version techniques), JWT signing forgery (SignSaboteur), CSS-based data exfiltration, WebSocket analysis and exploitation, cache- and WAF-bypass techniques, timing and race‑or
