Description Meta CVSS: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:F/RL:O/RC:C (5.7) Problem 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. Solution Update to typo3/html-sanitizer versions 1.0.7 or 2.0.16 that fix the problem described. Credits Thanks to David Klein who reported this issue, and to TYPO3 security team member Oliver Hader who fixed the issue.
