libhtml-formhandler-perl: HTML::FormHandler versions before 0.410002 for Perl render some error messages into HTML without escaping
CVE-2026-85485 is fixed in libhtml-formhandler-perl on 1 platform by DEBIAN-CVE-2026-85485 (version 0.410002-1), released September 17, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
