CVE-2026-85485 (GCVE-0-2026-85485)

Vulnerability from cvelistv5 – Published: 2026-09-08 20:09 – Updated: 2026-09-10 17:49

Title

HTML::FormHandler versions before 0.410002 for Perl render some error messages into HTML without escaping

Summary

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.

GHSA-M5H3-W9R6-P935

Vulnerability from github – Published: 2026-09-08 21:34 – Updated: 2026-09-10 18:31

Details

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.

Severity

6.1 (Medium)
