Cross-Site Scripting (XSS) Cheat Sheet
PortSwigger's XSS cheat sheet lists filter-bypass patterns for script injection across major browsers, without a new CVE.
PortSwigger's Cross-Site Scripting cheat sheet is a reference of payload patterns intended to bypass XSS filters in major browsers. The entries describe families of tricks such as exception handling, template strings, location and window-name redirects, ES6 language features, uppercase script tags, and dense JavaScript encodings. It is a long-standing Web Security Academy resource rather than disclosure of a new vulnerability or an active campaign. The listing names no CVE, affected product incident, or confirmed in-the-wild exploitation.
