CVE-2026-47344
Low · 2.1
CWE-79 Jun 8, 2026
TYPO3 HTML Sanitizer allows Cross-Site Scripting
When ALLOW_INSECURE_RAW_TEXT is enabled, whitespace-variant closing tags (e.g., </style\t>) are not recognized by the sanitizer but accepted by browsers as valid end tags, allowing subsequent content to escape sanitization. This allows bypassing the cross-site scripting prevention mechanism of typo3/html-sanitizer before version 2.3.2.
