  - Due to an encoding issue in the serialization layer, malicious markup nested in a noscript element was not
    encoded correctly. noscript is disabled in the default configuration, but might have been enabled in
    custom scenarios. This allows bypassing the cross-site scripting mechanism of typo3/html-sanitizer.
