WordPress · Eventprime · CVE-2026-1655
**Name of the Vulnerable Software and Affected Versions**
EventPrime plugin for WordPress versions prior to 4.2.8.5
**Description**
The EventPrime plugin for WordPress is susceptible to unauthorized post modification because of absent authorization checks. The `save frontend event submission` function accepts a user-controlled `event id` parameter and updates the corresponding event post without verifying ownership or capabilities. This allows authenticated attackers with Customer+ privileges to modify posts created by administrators by manipulating the `event id` parameter, provided they have a valid nonce.
**Recommendations**
Update the EventPrime plugin to version 4.2.8.5 or later.
