Payload is a free and open source headless content management system. In versions from 3.0.0 before 3.90.0 and canary versions before 4.0.0-canary.34, users with ordinary read access to other authentication documents in a collection with useAPIKey enabled can obtain active API keys and exercise the target accounts' permissions until those keys are rotated or disabled. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
