Text_Filter/lib/Horde/Text/Filter/Xss.php in Horde Application Framework before 3.3.6, Horde Groupware before 1.2.5, and Horde Groupware Webmail Edition before 1.2.5 does not properly handle data: URIs, which allows remote attackers to conduct cross-site scripting (XSS) attacks via data:text/html values for the HREF attribute of an A element in an HTML e-mail message. NOTE: the vendor states that the issue is caused by "an XSS vulnerability in Firefox browsers."

Security readout for executives and security teams

This is an old Horde webmail XSS issue where specially crafted HTML email links could run script in a user's browser. It matters mainly for organizations still running pre-2009 Horde releases. The public bundle does not show current exploitation, CVSS scoring, or CISA KEV listing. Exposure is most likely in legacy Horde Application Framework before 3.3.6, Horde Groupware before 1.2.5, or Horde Groupware Webmail Edition before 1.2.5 installations that render HTML email for users. Treat this as a legacy exposure cleanup item unless affected Horde is still in production. If present on an internet-accessible mail system, prioritize upgrade or retirement because email-driven XSS can affect user sessions and trust. Mitigation focus: Upgrade Horde Application Framework to 3.3.6 or later if still present.; Upgrade Horde Groupware to 1.2.5 or later if still present.; Upgrade Horde Groupware Webmail Edition to 1.2.5 or later if still present..
