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. This affects <= v1.19.3, <= v1.18.10, <= v1.17.13, < v1.20.0-alpha2.

Affected

Affected range stops below 1.20.0-alpha2, so it looks safe — our inference, not a vendor statement
