Due to a parsing issue in upstream package masterminds/html5, malicious markup used in a sequence with special HTML comments cannot be filtered and sanitized. This allows to by-pass the cross-site scripting mechanism of typo3/html-sanitizer.
Update to typo3/html-sanitizer versions 1.0.7 or 2.0.16 that fix the problem described.
Thanks to David Klein who reported this issue, and to TYPO3 security team member Oliver Hader who fixed the issue.
