CVE-2021-32667

Estado: ModificadaMedia (5.4)—

TYPO3 is an open source PHP based web content management system. Versions 9.0.0 through 9.5.28, 10.0.0 through 10.4.17, and 11.0.0 through 11.3.0 have a cross-site scripting vulnerability. When _Page TSconfig_ settings are not properly encoded, corresponding page preview module (_Web>View_) is vulnerable to persistent cross-site scripting. A valid backend user account is needed to exploit this vulnerability. TYPO3 versions 9.5.29, 10.4.18, 11.3.1 contain a patch for this issue.
