TYPO3 is an open source PHP based web content management system. In versions 9.0.0 through 9.5.27, 10.0.0 through 10.4.17, and 11.0.0 through 11.3.0, user credentials may been logged as plain-text. This occurs when explicitly using log level debug, which is not the default configuration. TYPO3 versions 9.5.28, 10.4.18, 11.3.1 contain a patch for this vulnerability.

Weakness

Information written to log files can be of a sensitive nature and give valuable guidance to an attacker or expose sensitive user information.
