When ALLOW_INSECURE_RAW_TEXT is enabled, whitespace-variant closing tags (e.g., ) 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.
