Ceph does not properly sanitize encryption keys in debug logging for v4 auth. This results in the leaking of encryption key information in log files via plaintext. Versions up to v13.2.4 are vulnerable.
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:
