Detection Guidance

You can detect this vulnerability by checking if the EventPrime plugin version is up to and including 4.2.7.0 and if the REST API is enabled. Since the vulnerability allows unauthenticated access to sensitive booking data via the REST API, monitoring REST API requests to EventPrime endpoints for unusual or unauthorized access patterns can help detect exploitation attempts. Specific commands could include using curl or similar tools to query the REST API endpoints to see if sensitive data is exposed without authentication. For example, you might run: curl -X GET https://yourwordpresssite.com/wp-json/eventprime/v1/bookings to check if booking data is accessible without credentials. Additionally, reviewing web server logs for unauthenticated REST API calls to EventPrime endpoints can help detect attempts. However, no explicit detection commands are provided in the resources.

Mitigation Strategies

The immediate step to mitigate this vulnerability is to update the EventPrime plugin to version 4.2.7.0 or later, as this version includes partial patches addressing CVE-2025-14507. Ideally, update to the latest version available (e.g., 4.2.8.0) which includes further improvements and security fixes. Additionally, if possible, disable or restrict access to the EventPrime REST API endpoints until the update is applied. Monitoring and limiting unauthenticated access to the REST API can reduce exposure. Applying the official plugin update from the WordPress repository is the recommended mitigation. [1, 2]
