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.
