Hi,
The following vulnerability was published for php-horde-text-filter.
CVE-2021-26929[0]:
| An XSS issue was discovered in Horde Groupware Webmail Edition through
| 5.2.22 (where the Horde_Text_Filter library before 2.3.7 is used). The
| attacker can send a plain text e-mail message, with JavaScript encoded
| as a link or email that is mishandled by preProcess in Text2html.php,
| because bespoke use of \x00\x00\x00 and \x01\x01\x01 interferes with
| XSS defenses.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
