CVE-2026-85485 Details
Description
HTML::FormHandler versions before 0.410002 for Perl render some error messages into HTML without escaping. The Table form layout and the Bootstrap 2 and 3 wrappers splice each error string straight into the surrounding markup. Version 0.410000, the fix for CVE-2026-19872, escaped the equivalent values in the other layouts and wrappers, and 0.410002 extended that to these three. Error messages that contain attacker-influenced content such as rejected field values could embed JavaScript in rendered pages.
A vulnerability exists in HTML::FormHandler versions prior to 0.410002 for Perl, where error messages are rendered into HTML without proper escaping. This issue is present in the Table form layout and the Bootstrap 2 and 3 wrappers, which insert error strings directly into the HTML markup. As a result, error messages containing user-supplied data, such as rejected field values, could be exploited to inject JavaScript into the rendered page.
Users can upgrade to HTML::FormHandler version 0.410002 or later, where this vulnerability has been fixed.
