Name of the Vulnerable Software and Affected Versions Tournamatch plugin for WordPress versions up to and including 4.6.1

Description The issue is related to Stored Cross-Site Scripting via the 'trn-ladder-registration-button' shortcode. This is due to insufficient input sanitization and output escaping on user-supplied attributes. Authenticated attackers with contributor-level access or higher can inject arbitrary web scripts in pages that will execute when a user accesses an injected page.

Recommendations For versions up to and including 4.6.1, update to a version higher than 4.6.1 to resolve the issue. As a temporary workaround, consider disabling the 'trn-ladder-registration-button' shortcode until a patch is available. Restrict access to the Tournamatch plugin to minimize the risk of exploitation, especially for users with contributor-level access or higher.
