CVE-2025-6258

Name of the Vulnerable Software and Affected Versions: WP SoundSystem plugin for WordPress versions up to, and including, 3.4.2

Description: The issue is related to Stored Cross-Site Scripting via the plugin's wpsstm-track shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows 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.

Recommendations: For WP SoundSystem plugin for WordPress versions up to, and including, 3.4.2, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the wpsstm-track shortcode to minimize the risk of exploitation.
