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.
