Stored XSS in Makesweat for WordPress 0.1 and earlier allows remote authenticated users to execute scripts through the club ID setting. The setting update path stores makesweat_clubid without sufficient sanitization, and the plugin renders the saved value without output escaping. Administrator-level access is required; injected JavaScript runs in the browser of any user who opens a page containing the stored value.
