What the vulnerability does
01Description
The Simple Football Scoreboard plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'ytmr_fb_scoreboard' shortcode in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

An authenticated user can inject malicious scripts that execute in other users' browsers, potentially stealing session data or performing actions on their behalf. The vulnerability affects the application scope, meaning impacts may extend beyond the scoreboard component itself.
