Adds
offensive-web-cache-poisoningunderweb.Coverage: fingerprinting cacheable responses (Cache-Control/Age/X-Cache/CDN headers); discovering unkeyed inputs (X-Forwarded-Host/-Scheme/-For, X-Host, X-Original-URL) with Burp Param Miner; weaponizing into stored XSS, resource-import hijacking, malicious redirects, and CPDoS; advanced key abuse (cache key injection, fat GET, parameter cloaking, normalization/delimiter confusion, multi-cache/CDN quirks); and web cache deception via path confusion (
/account.php/x.css,/profile/..%2fx.css) to cache authenticated pages for anonymous retrieval; plus the defender view.Follows the SKILL.md format with Key References to James Kettle (PortSwigger Research), Omer Gil's Web Cache Deception, and CWE-444/525/639.
