CVE-2025-4594
The Tournamatch plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'trn-ladder-registration-button' shortcode in all versions up to, and including, 4.6.1 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.
