AI-suggested

European organizations should immediately audit their WordPress installations to identify the presence of the Wp-Adv-Quiz plugin and its version. Until an official patch is released, administrators should consider disabling or uninstalling the plugin if it is not essential. For sites requiring the plugin, restrict admin access strictly and monitor for unusual administrative activity. Implement Web Application Firewall (WAF) rules to detect and block suspicious payloads targeting plugin settings. Additionally, enforce strong authentication mechanisms such as multi-factor authentication (MFA) for all admin users to reduce the risk of credential compromise. Regularly review and sanitize all user inputs and plugin settings manually if possible. Organizations should subscribe to vulnerability feeds and update the plugin promptly once a patch is available. Finally, conduct security awareness training for administrators about the risks of stored XSS and safe plugin management practices.

Description

The Wp-Adv-Quiz WordPress plugin through 1.0.2 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).
