Technical details

A missing authorization vulnerability (CWE-862) exists in the EventPrime plugin for WordPress up to version 4.3.2.0. The flaw stems from insufficient validation of user permissions when accessing certain functions or security levels, allowing an unauthenticated attacker to execute actions that should be restricted to higher-privileged users. The attack vector is remote via the network with no user interaction required. Successful exploitation allows an attacker to modify data (Integrity: High) but does not directly lead to data disclosure or service downtime according to the CVSS vector. The issue is resolved in version 4.3.2.1.
