Sentry is an error tracking and performance monitoring platform. Prior to 24.4.1, when authenticating as a superuser to Sentry with a username and password, the password is leaked as cleartext in logs under the event: "auth-index.validate_superuser". An attacker with access to the log data could use these leaked credentials to login to the Sentry system as superuser. Self-hosted users on affected versions should upgrade to 24.4.1 or later. Users can configure the logging level to exclude logs of the "INFO" level and only generate logs for levels at "WARNING" or more.
