NVD description

The Events Calendar WordPress plugin before 6.16.5.1 does not perform an authorization check on one of its Event Aggregator import REST API routes and skips an integrity check for a particular status value, allowing unauthenticated attackers to mark existing import records as failed and to store arbitrary content in a hidden comment record.
