What happened

PortSwigger Research feed aggregating web security research from 2023–2026. Key topics include SAML authentication bypasses, HTTP request smuggling and desynchronization, cookie-prefix and HttpOnly bypasses, URL-validation flaws affecting SSRF/CORS/open redirects, web cache attacks, CSS/XSS data exfiltration, signed-token forgery, CSP bypasses, parser discrepancies, and race-condition exploitation. Several entries describe potentially critical authentication and authorization bypass techniques, but the feed itself does not identify specific CVEs.
