Description

The EventON Action User plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.5.14. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to grant EventON management capabilities and the upload_files capability to any non-administrator WordPress role or user, escalating their privileges within the site. The administrator role is protected by an early-return guard in update_role_caps(), so only non-administrator roles and individual users can be targeted; however, the same unauthenticated exposure also allows attackers to enumerate all WordPress users with their IDs and display names, disclose role and user capability state along with nonce values, and tamper with event-to-user term assignments.
