[jira] [Created] (KAFKA-14623) OAuth's HttpAccessTokenRetriever potentially leaks secrets in logging

Kirk True created KAFKA-14623:
---------------------------------

             Summary: OAuth's HttpAccessTokenRetriever potentially leaks secrets in logging  
                 Key: KAFKA-14623
                 URL: https://issues.apache.org/jira/browse/KAFKA-14623
             Project: Kafka
          Issue Type: Bug
          Components: clients, security
    Affects Versions: 3.3.1
            Reporter: Kirk True


The OAuth code that communicates via HTTP with the IdP (HttpAccessTokenRetriever.java) includes logging that outputs the request and response payloads. Among them are:
 * [https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/common/security/oauthbearer/internals/secured/HttpAccessTokenRetriever.java#L265]
 * [https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/common/security/oauthbearer/internals/secured/HttpAccessTokenRetriever.java#L274]
 * [https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/common/security/oauthbearer/internals/secured/HttpAccessTokenRetriever.java#L320]

It should be determined if there are other places sensitive information might be inadvertently exposed.
