TYPO3 is an open source PHP based web content management system released under the GNU GPL. In typo3 installations there are always at least two different sites. Eg. first.example.org and second.example.com. In affected versions a session cookie generated for the first site can be reused on the second site without requiring additional authentication. This vulnerability has been addressed in versions 8.7.55, 9.5.44, 10.4.41, 11.5.33, and 12.4.8. Users are advised to upgrade. There are no known workarounds for this vulnerability.

TYPO3 is an open source PHP based web content management system released under the GNU GPL. In affected versions the login screen of the standalone install tool discloses the full path of the transient data directory (e.g. /var/www/html/var/transient/). This applies to composer-based scenarios only - “classic” non-composer installations are not affected. This issue has been addressed in version 12.4.8. Users are advised to upgrade. There are no known workarounds for this vulnerability.

TYPO3 is an open source PHP based web content management system released under the GNU GPL. In affected versions DOM processing instructions are not handled correctly. This allows bypassing the cross-site scripting mechanism of typo3/html-sanitizer. This vulnerability has been addressed in versions 1.5.3 and 2.1.4. Users are advised to upgrade. There are no known workarounds for this vulnerability.

TYPO3 is an open source PHP based web content management system. Starting in version 9.4.0 and prior to versions 9.5.42 ELTS, 10.4.39 ELTS, 11.5.30, and 12.4.4, in multi-site scenarios, enumerating the HTTP query parameters `id` and `L` allowed out-of-scope access to rendered content in the website frontend. For instance, this allowed visitors to access content of an internal site by adding handcrafted query parameters to the URL of a site that was publicly available. TYPO3 versions 9.5.42 ELTS, 10.4.39 ELTS, 11.5.30, 12.4.4 fix the problem.
