CVE-2026-32583

Vulnerability

Overview The Modern Events Calendar plugin for WordPress versions up to 7.29.0 contains a missing authorization vulnerability. This flaw allows exploitation of incorrectly configured access control security levels, meaning that functions or endpoints that should require authentication or specific permissions are accessible without proper checks [1].

Exploitation

An unauthenticated or low-privileged attacker can exploit this broken access control to perform actions intended for higher-privileged users. The vulnerability does not require authentication, making it easy to exploit remotely. According to the advisory, such vulnerabilities are commonly used in mass-exploit campaigns targeting thousands of websites regardless of size [1].

Impact

Successful exploitation could allow an attacker to modify event data, access sensitive information, or perform other unauthorized operations within the plugin. The exact impact depends on the specific missing authorization, but it can lead to data integrity issues and unauthorized access to administrative functions.

Mitigation

The vendor has not yet released a patch beyond version 7.29.0. Users are strongly advised to update the plugin as soon as a patched version becomes available. If immediate updating is not possible, consult with a hosting provider or web developer for temporary workarounds [1].
