CVE-2020-8565

Name of the Vulnerable Software and Affected Versions Kubernetes versions prior to v1.20.0-alpha2 Kubernetes versions 1.19.3 and earlier Kubernetes versions 1.18.10 and earlier Kubernetes versions 1.17.13 and earlier

Description In Kubernetes, if the logging level is set to at least 9, authorization and bearer tokens will be written to log files. This can occur both in API server logs and client tool output like kubectl.

Recommendations For versions prior to v1.20.0-alpha2, consider reducing the logging level to prevent sensitive information from being written to log files. For versions 1.19.3 and earlier, update to a version later than v1.19.3 to mitigate the risk. For versions 1.18.10 and earlier, update to a version later than v1.18.10 to mitigate the risk. For versions 1.17.13 and earlier, update to a version later than v1.17.13 to mitigate the risk. As a temporary workaround, consider disabling debug-level logging until a patch is available.
