Last modified

CVE-2026-85630 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. HTML::FormHandler versions before 0.410002 for Perl render field attributes into HTML without escaping using the process_attrs method. Any application with fields or field labels where some attributes are built from data rather than literals allows attacker-influenced text in an attribute value that can override the field attributes or embed JavaScript in rendered pages. For example, the RadioGroup widget uses the process_attrs method via the render_option and wrap_radio methods.. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
