Cross Site Smallish Scripting (XSSS)

This technical blog describes multiple methods for exploiting client-side XSS when input length is limited, including compact script tags, dynamic importing/fetching of external scripts, CORS considerations, splitting payloads across multiple inputs or comments, using base64/localStorage to assemble payloads, and techniques to bypass innerHTML/CSP restrictions; it concludes with defensive recommendations for CSP, WAF/XSS protections, and output encoding.
