Root Cause Analysis
The vulnerability stems from two functions in the VSphere cloud provider implementation that logged Secret objects with verbosity level 4. The commit 247f6dd
shows these functions originally used '%+v' formatting which exposes secret contents. The CVE description explicitly mentions credential leakage via cloud controller manager logs at log level 4+, and the patch modifies these exact functions to remove sensitive data from logs.
