CVE-2026-13441 High · 7.2 CWE-79 Jul 9, 2026

EventPrime <= 4.3.4.2 - Unauthenticated Stored Cross-Site Scripting via 'new_event_type_background_color' Parameter

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-2026-1655 Medium · 4.3 CWE-862 Feb 18, 2026

EventPrime <= 4.2.8.4 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Event Modification via 'event_id' Parameter

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-2026-1657 Medium · 5.3 CWE-862 Feb 17, 2026

EventPrime <= 4.2.8.4 - Missing Authorization to Unauthenticated Image Upload via 'ep_upload_file_media' AJAX Endpoint

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-2025-14507 Medium · 5.3 CWE-200 Jan 13, 2026

EventPrime - Events Calendar, Bookings and Tickets <= 4.2.7.0 - Unauthenticated Sensitive Information Exposure via REST API

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-2025-12498 Medium · 4.3 CWE-862 Nov 8, 2025

EventPrime – Events Calendar, Bookings and Tickets <= 4.2.0.0 - Missing Authorization to Authenticated (Subscriber+) Booking Note Creation

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.
