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

Vulnerability from cvelistv5 – Published: 2026-09-08 20:09 – Updated: 2026-09-10 17:48

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.

GHSA-4QF4-6X5X-M29P

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 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

6.1 (Medium)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
