Typo3 · Sanitize-Html · CVE-2026-47344
**Name of the Vulnerable Software and Affected Versions**
typo3/html-sanitizer versions prior to 2.3.2
**Description**
When the `ALLOW INSECURE RAW TEXT` setting is enabled, the sanitizer fails to recognize closing tags containing whitespace variants, such as `</stylet>`. Because browsers interpret these as valid end tags, subsequent content can escape the sanitization process, enabling a bypass of the cross-site scripting prevention mechanism.
**Recommendations**
Update to version 2.3.2 or later.
As a temporary mitigation, disable the `ALLOW INSECURE RAW TEXT` setting.
