This vulnerability in The Events Calendar plugin arises from missing authorization checks, which means that users with limited privileges may perform actions beyond their intended permissions. The issue affects all versions up to 6.11.2.1. The CVSS 3.1 base score is 5.4, reflecting network attack vector, low attack complexity, low privileges required, no user interaction, unchanged scope, no confidentiality impact, but integrity and availability impacts. No patch or vendor advisory is currently available, and the plugin is not a cloud service.

Exploitation of this vulnerability could allow an attacker with low privileges to perform unauthorized actions that may alter data integrity or availability within the affected plugin. There is no impact on confidentiality. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor the vendor's communications for updates. Until a fix is available, consider restricting access privileges to trusted users only and review plugin configurations to minimize exposure.
