The Events Manager - Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Stored Cross-Site Scripting via event attribute values in all versions up to, and including, 7.3.3. This is due to insufficient input sanitization when storing attribute values (using only `wp_unslash()` without sanitization) and lack of output escaping when rendering the '#_ATT{key}' placeholder. This makes it possible for authenticated attackers, with Author-level access and above, or unauthenticated attackers when anonymous event submissions are enabled, to inject arbitrary web scripts that execute when any user views the affected event page.
The Events Manager – Calendar, Bookings, Tickets, and more! WordPress plugin is vulnerable to a Local File Inclusion (LFI) flaw in all versions up to and including 7.3.7.4. Authenticated attackers with administrator-level privileges can exploit this vulnerability via the em_options_save function to include and execute arbitrary PHP files on the server. Once a malicious file inclusion key is stored, it is executed on every admin_init event, including unauthenticated admin-ajax.php requests, enabling code execution without further authentication.
The Events Manager – Calendar, Bookings, Tickets, and more! WordPress plugin contains a reflected cross-site scripting (XSS) vulnerability in the 'header_format' parameter. This affects all versions up to and including 7.4.0.1. The vulnerability arises because the 'search_events_grouped' AJAX action does not sanitize this parameter, allowing unauthenticated attackers to inject arbitrary scripts that execute when a user interacts with crafted content.
The Events Manager – Calendar, Bookings, Tickets, and more! WordPress plugin up to version 7.4.0 contains an authorization bypass vulnerability. This flaw allows unauthenticated attackers to access event details such as titles, dates, descriptions, and locations that are marked as draft, pending, trashed, or private by administrators. The vulnerability arises from improper verification of user authorization before granting access to these event details.
The Events Manager plugin for WordPress contains a SQL injection vulnerability in versions up to and including 7.4.0. Authenticated users with contributor-level access or higher can exploit this by injecting SQL metacharacters into a custom meta key, which is later used unsafely in a database query during event or location duplication actions. This vulnerability allows attackers to extract sensitive information from the database without requiring user interaction.
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 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.
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 Stored Cross-Site Scripting via the plugin's shortcodes in all versions up to, and including, 7.0.3 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 Reflected Cross-Site Scripting via the ‘calendar_header’ parameter in all versions up to, and including, 7.0.3 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 Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to time-based SQL Injection via the ‘orderby’ parameter in all versions up to, and including, 7.0.3 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.
The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to time-based SQL Injection via the active_status parameter in all versions up to, and including, 6.6.3 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.
The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘country’ parameter in all versions up to, and including, 6.4.8 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 Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'event', 'location', and 'event_category' shortcodes in all versions up to, and including, 6.4.7.3 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 Cross-Site Request Forgery in all versions up to, and including, 6.4.7.1. This is due to missing or incorrect nonce validation on several actions. This makes it possible for unauthenticated attackers to modify booking statuses via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
The Meta Tag Manager plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.0.2 via deserialization of untrusted input in the get_post_data function. This makes it possible for authenticated attackers, with contributor access or higher, to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the physical location value in all versions up to, and including, 6.4.7.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The Events Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 6.4.6.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
