The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'header_format' parameter in all versions up to, and including, 7.4.0.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The shortcode entry point sanitizes 'header_format' via wp_kses(), but the unauthenticated 'search_events_grouped' AJAX action bypasses this sanitization entirely, leaving the parameter unsanitized before it is echoed into the HTML body in output_grouped().

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 7.3.7.4 via the em_options_save function. This makes it possible for authenticated attackers, with administrator-level access and above, to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included. The stored traversal key is subsequently executed via an include_once() call that fires on every admin_init invocation — including unauthenticated admin-ajax.php requests — meaning once the malicious key is stored by an administrator, the inclusion is triggered without any further authentication or capability check.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 7.4.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to view the titles, dates, descriptions, and location details of events and locations that administrators have marked as draft, pending, trashed, or private.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to generic SQL Injection via Stored 'meta_key' via Event/Location Duplicate Action in all versions up to, and including, 7.4.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This is a second-order SQL injection: an attacker first plants SQL metacharacters in a custom meta key via the standard add-meta flow (WordPress stores these verbatim in wp_postmeta), then triggers the injection by invoking the event_duplicate or location_duplicate action, which reads the stored meta keys via get_post_meta() and concatenates them unsafely into the INSERT query.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'events_list_grouped' shortcode in all versions up to, and including, 7.2.2.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for 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.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 7.2.2.2 via the 'get_location' action due to insufficient restrictions on which locations can be included. This makes it possible for unauthenticated attackers to extract data from password protected, private, or draft event locations that they should not have access to.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 7.2.2.2. This is due to missing or incorrect nonce validation on the 'location_delete' action. This makes it possible for unauthenticated attackers to delete locations via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
