TYPO3 is an open source PHP based web content management system released under the GNU GPL. It has been discovered that the `FileDumpController` (backend and frontend context) is vulnerable to cross-site scripting when malicious files are displayed using this component. A valid backend user account is needed to exploit this vulnerability. Update to TYPO3 version 7.6.58 ELTS, 8.7.48 ELTS, 9.5.37 ELTS, 10.4.32 or 11.5.16 that fix the problem. There are no known workarounds for this issue.

TYPO3 is an open source PHP based web content management system released under the GNU GPL. It has been discovered that the `f:asset.css` view helper is vulnerable to cross-site scripting when user input is passed as variables to the CSS. Update to TYPO3 version 10.4.32 or 11.5.16 that fix the problem. There are no known workarounds for this issue.

TYPO3 is an open source PHP based web content management system released under the GNU GPL. It has been discovered that observing response time during user authentication (backend and frontend) can be used to distinguish between existing and non-existing user accounts. Extension authors of 3rd party TYPO3 extensions providing a custom authentication service should check if the extension is affected by the described problem. Affected extensions must implement new `MimicServiceInterface::mimicAuthUser`, which simulates corresponding times regular processing would usually take. Update to TYPO3 version 7.6.58 ELTS, 8.7.48 ELTS, 9.5.37 ELTS, 10.4.32 or 11.5.16 that fix this problem. There are no known workarounds for this issue.

TYPO3 is an open source PHP based web content management system released under the GNU GPL. It has been discovered that the expiration time of a password reset link for TYPO3 backend users has never been evaluated. As a result, a password reset link could be used to perform a password reset even if the default expiry time of two hours has been exceeded. Update to TYPO3 version 10.4.32 or 11.5.16 that fix the problem. There are no known workarounds for this issue.

TYPO3 is an open source PHP based web content management system released under the GNU GPL. In affected versions requesting invalid or non-existing resources via HTTP triggers the page error handler which again could retrieve content to be shown as an error message from another page. This leads to a scenario in which the application is calling itself recursively - amplifying the impact of the initial attack until the limits of the web server are exceeded. Users are advised to update to TYPO3 version 11.5.16 to resolve this issue. There are no known workarounds for this issue.

The typo3/html-sanitizer package is an HTML sanitizer, written in PHP, aiming to provide XSS-safe markup based on explicitly allowed tags, attributes and values. Due to a parsing issue in the upstream package `masterminds/html5`, malicious markup used in a sequence with special HTML comments cannot be filtered and sanitized. This allows for a bypass of the cross-site scripting mechanism of `typo3/html-sanitizer`. This issue has been addressed in versions 1.0.7 and 2.0.16 of the `typo3/html-sanitizer` package. Users are advised to upgrade. There are no known workarounds for this issue.
