The Membership Plugin – Restrict Content plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.2.13 via the WordPress core search feature.

The Events Calendar WordPress plugin before 6.4.0.1 does not properly sanitize user-submitted content when rendering some views via AJAX.

The Events Calendar WordPress plugin before 6.8.2.1 is missing access checks in the REST API, allowing for unauthenticated users to access information about password protected events.

The The Events Calendar plugin for WordPress is vulnerable to SQL Injection via the 'order' parameter of the 'tribe_has_next_event' function in all versions up to, and including, 6.6.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Only sites that have manually added tribe_has_next_event() will be vulnerable to this SQL injection.

The Events Calendar WordPress plugin before 6.6.4 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).
