Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache ZooKeeper versions 3.9.0 to before 3.9.5 and 3.8.0 to before 3.8.6 are affected. Improper handling of configuration values in ZKConfig can expose sensitive information from client configuration in the client's log file at INFO level, and the source does not say what access an attacker needs to read those logs. Upgrade to ZooKeeper 3.9.5 or 3.8.6, which fix the issue.
