When an administrator views the DNS configuration of an affected domain, the payload executes automatically — enabling complete admin account takeover, credential theft, and full server compromise.\n\n---\n\n### Details\n\nThree code locations combine to create this vulnerability:\n\n**1. Input validation does not strip HTML special characters** — `lib/Froxlor/Api/Commands/DomainZones.php:158`\n\n```php\n// Only strips non-printable chars.  (0x3C/0x3E) pass through unmodified.\n$content = preg_replace('/[^\\x09\\x20-\\x7E]/', '', $content);\n$content = Dns::encloseTXTContent($content);  // only wraps in quotes, no HTML encoding\n```\n\n**2. Display callback returns raw HTML without escaping** — `lib/Froxlor/UI/Callbacks/Text.php:95`\n\n```php\npublic static function wordwrap(array $attributes): string {\n    return wordwrap($attributes['data'], 100, '', true);  // no htmlspecialchars()\n}\n```\n\n**3.
