CVE-2026-85630 (GCVE-0-2026-85630)

Vulnerability from cvelistv5 – Published: 2026-09-08 20:09 – Updated: 2026-09-08 22:07

Title

HTML::FormHandler versions before 0.410002 for Perl render field attributes into HTML without escaping using the process_attrs method

Summary

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.

Severity

No CVSS data available.

CWE

Vulnerability from github – Published: 2026-09-08 21:34 – Updated: 2026-09-09 00:30

Details

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.
