- CVE-2026-13441, 9 Jul 2026
- The EventPrime - Events Calendar, Bookings and Tickets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'new_event_type_background_color' parameter in all versions up to, and including, 4.3.4.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the plugin's Guest Submissions setting (allow_submission_by_anonymous_user) to be enabled, which allows unauthenticated attackers to submit event types via the frontend form; when that setting is disabled, exploitation requires at minimum a subscriber-level authenticated account. CVE record
- CVE-2026-1655, 18 Feb 2026
- The EventPrime plugin for WordPress is vulnerable to unauthorized post modification due to missing authorization checks in all versions up to, and including, 4.2.8.4. This is due to the save_frontend_event_submission function accepting a user-controlled event_id parameter and updating the corresponding event post without enforcing ownership or capability checks. This makes it possible for authenticated (Customer+) attackers to modify posts created by administrators by manipulating the event_id parameter granted they can obtain a valid nonce. CVE record
- CVE-2026-1657, 17 Feb 2026
- The EventPrime plugin for WordPress is vulnerable to unauthorized image file upload in all versions up to, and including, 4.2.8.4. This is due to the plugin registering the upload_file_media AJAX action as publicly accessible (nopriv-enabled) without implementing any authentication, authorization, or nonce verification despite a nonce being created. This makes it possible for unauthenticated attackers to upload image files to the WordPress uploads directory and create Media Library attachments via the ep_upload_file_media endpoint. CVE record
- CVE-2025-14507, 13 Jan 2026
- The EventPrime - Events Calendar, Bookings and Tickets plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.2.7.0 via the REST API. This makes it possible for unauthenticated attackers to extract sensitive booking data including user names, email addresses, ticket details, payment information, and order keys when the API is enabled by an administrator. The vulnerability was partially patched in version 4.2.7.0. CVE record
- CVE-2025-12498, 8 Nov 2025
- The EventPrime - Events Calendar, Bookings and Tickets plugin for WordPress is vulnerable to unauthorized booking note creation due to a missing capability check on the 'booking_add_notes' function in all versions up to, and including, 4.2.0.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to add a note to the backend view of any booking. CVE record
- CVE-2024-4665, 15 May 2025
- The EventPrime WordPress plugin before 3.5.0 does not properly validate permissions when updating bookings, allowing users to change/cancel bookings for other users. Additionally, the feature is lacking a nonce. CVE record
- CVE-2024-13526, 7 Mar 2025
- The EventPrime - Events Calendar, Bookings and Tickets plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability checks on the export_submittion_attendees function in all versions up to, and including, 4.0.7.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to download list of attendees for any event. CVE record
- CVE-2024-12024, 17 Dec 2024
- The EventPrime - Events Calendar, Bookings and Tickets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the em_ticket_category_data and em_ticket_individual_data parameters in all versions up to, and including, 4.0.7.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever an administrative user accesses an injected page. Note: this vulnerability requires the "Guest Submissions" setting to be enabled. It is disabled by default. CVE record
- CVE-2024-8369, 10 Sep 2024
- The EventPrime - Events Calendar, Bookings and Tickets plugin for WordPress is vulnerable to unauthorized access to Private or Password-protected events due to missing authorization checks in all versions up to, and including, 4.0.4.3. This makes it possible for unauthenticated attackers to view private or password-protected events. CVE record
- CVE-2024-1127, 13 Mar 2024
- The EventPrime - Events Calendar, Bookings and Tickets plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the booking_export_all() function in all versions up to, and including, 3.4.1. This makes it possible for authenticated attackers, with subscriber-level access and above, to retrieve all event booking which can contain PII. CVE record
- CVE-2023-6447, 22 Jan 2024
- The EventPrime WordPress plugin before 3.3.6 lacks authentication and authorization, allowing unauthenticated visitors to access private and password protected Events by guessing their numeric id/event name. CVE record

What to do if you run EventPrime
If you run EventPrime, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
