Admidio is an open-source user management solution. Prior to version 5.0.10, when debug logging is enabled, `Session::setCookie()` logs full cookie values and `Session::start()` logs the current session ID. In a real Admidio deployment this includes both the active session cookie and the persistent auto-login cookie. Anyone with access to the log sink can recover live bearer-style credentials from the logs. Version 5.0.10 contains a fix.
