A flaw was found in OpenShift Container Platform version 4.1 and later. Sensitive information was found to be logged by the image registry operator allowing an attacker able to gain access to those logs, to read and write to the storage backing the internal image registry. The highest threat from this vulnerability is to data integrity.
Information written to log files can be of a sensitive nature and give valuable guidance to an attacker or expose sensitive user information.

While logging all information may be helpful during development stages, it is important that logging levels be set appropriately before a product ships so that sensitive user data and system information are not accidentally exposed to potential attackers. Different log files may be produced and stored for:
