YugabyteDB is vulnerable to cross site scripting (XSS) via log injection. Writing invalidated user input to log files can allow an unprivileged attacker to forge log entries or inject malicious content into the logs.
The controller responsible for setting the logging level does not include any authorization
checks to ensure the user is authenticated. This can be seen by noting that it extends
Controller rather than AuthenticatedController and includes no further checks. This issue affects YugabyteDB Anywhere: from 2.0.0 through 2.17.3
