CVE-2025-4796: 
WordPress vulnerability analysis and mitigation

The Eventin plugin for WordPress contains a privilege escalation vulnerability via account takeover in versions up to and including 4.0.34. This vulnerability was assigned CVE-2025-4796 and was disclosed on August 8, 2025. The issue affects the plugin's speaker management functionality and allows attackers with contributor-level permissions or higher to potentially take over administrator accounts (NVD).

The vulnerability exists in the 'Eventin\Speaker\Api\SpeakerController::update_item' function due to improper validation of user identity and capabilities before updating user details like email addresses. The vulnerability has been assigned a CVSS v3.1 base score of 8.8 (HIGH) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. It is classified as CWE-639 (Authorization Bypass Through User-Controlled Key) (NVD, Wordfence).

The vulnerability allows authenticated attackers with contributor-level or higher permissions to modify any user's email address, including administrators. This capability can be exploited to perform password resets and gain unauthorized access to administrator accounts, potentially leading to complete site compromise (NVD).

Users should immediately update the Eventin plugin to a version newer than 4.0.34 once available. Until an update is released, site administrators should carefully review and potentially restrict user roles that have access to the plugin's functionality (NVD).
