**Name of the Vulnerable Software and Affected Versions** Themesflat Addons For Elementor plugin for WordPress versions up to, and including, 2.1.1 **Description** The issue is related to Stored Cross-Site Scripting via the plugin's widget's titles 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 versions up to, and including, 2.1.1, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the plugin's widget title editing feature to minimize the risk of exploitation. Additionally, restrict contributor-level access and above to only necessary personnel to reduce the potential attack surface.
