Important HTML banner changes
[!!!][TASK] Add extension setting to enable HTML banner type for editors
The output of HTML banners has most likely never worked as expected since the introduction of TYPO3 HTML sanitizer in TYPO3 v9.5, since the Fluid template used <f:format.html>
ViewHelper to output the content of a HTML banner. Since no one ever reported a problem with HTML banners until april 2024, it can be assumed, that the HTML banner feature is most likey unused.
As a result and due to security concerns, the feature has been disabled for non-admin users. If non-admin users are required to create HTML banners, the extension setting allowHtmlBannerForNonAdmins
must be enabled.
