Executive Summary

CVE-2026-32583 is a Broken Access Control vulnerability in the WordPress Modern Events Calendar plugin up to version 7.29.0. It occurs due to missing authorization, authentication, or nonce token checks in certain functions, which allows unauthenticated users to perform actions that normally require higher privileges.

This means that users without proper permissions can exploit the flaw to bypass security controls and access or manipulate features they should not be able to.

Impact Analysis

The vulnerability can allow unauthorized users to perform privileged actions on affected websites using the Modern Events Calendar plugin. However, the impact is considered low severity with a CVSS score of 5.3, indicating limited potential damage.

While it could be exploited in mass campaigns targeting many sites, it is unlikely to be widely exploited due to its low severity.

No official patch is currently available, so affected users should update the plugin when possible or seek help from hosting providers or developers to mitigate risks.
