Themes Vulnerabilities
Multiple Themes - Reflected Cross-Site Scripting via Customizer Notify
Description
The quality_customizer_notify_dismiss_action and ti_customizer_notify_dismiss_recommended_plugins AJAX actions (names can differ depending on the theme), available to authenticated users in multiple themes do not validate or escape the id parameter before outputting it back in the response, leading to Reflected Cross-Site Scripting issues. Furthermore, the actions are also missing CSRF and capability checks (however the risk is extremely low, only allowing attackers to dismiss recommendations).
