## Affected

- jmrukkers Wikiloops Track Player: through 1.0.1

## Description

The Wikiloops Track Player plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `wikiloops` shortcode in all versions up to, and including, 1.0.1 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.
