## Technical details

Stored cross-site scripting (XSS) in the 'url' parameter of the If-So Dynamic Content plugin allows authenticated contributors to inject arbitrary JavaScript via shortcodes. The vulnerability exists due to insufficient input sanitization and output escaping. Exploitation requires contributor-level WordPress access; the injected script executes in administrator sessions when the vulnerable post is previewed or accessed, enabling session hijacking or malicious administrative actions.
