Name of the Vulnerable Software and Affected Versions OpenShift API Server (affected versions not specified)

Description A flaw was found in the OpenShift API Server where it failed to sufficiently protect OAuthTokens by leaking them into the logs when an API Server panic occurred. This allows an attacker with the ability to cause an API Server error to read the logs and use the leaked OAuthToken to log into the API Server with the leaked token.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
