CVE-2026-121632 (GCVE-0-2026-121632)

Vulnerability from cvelistv5 – Published: 2026-11-04 14:23 – Updated: 2026-11-04 18:05

Title

Data::MuForm versions through 0.05 for Perl render attribute values and option labels into HTML without escaping

Summary

Data::MuForm versions through 0.05 for Perl render attribute values and option labels into HTML without escaping. process_attrs writes each attribute value into the markup as is. The select, radio group and checkbox group renderers pass each option to it, so an option's value becomes an unescaped attribute. Option and option group labels are also unescaped, the group label inside a label attribute and the others in element content. Any application whose option list is built from data rather than literals, using an options_<field_name> method, a build_options method or a DBIC model, allows attacker-influenced text in an option value or label that can embed JavaScript in rendered pages. Attribute values built from data, such as through element_attr, are affected the same way.

GHSA-7PVX-4MX6-W9XM

Vulnerability from github – Published: 2026-11-04 15:32 – Updated: 2026-11-04 21:32

Details

Data::MuForm versions through 0.05 for Perl render attribute values and option labels into HTML without escaping.

process_attrs writes each attribute value into the markup as is. The select, radio group and checkbox group renderers pass each option to it, so an option's value becomes an unescaped attribute. Option and option group labels are also unescaped, the group label inside a label attribute and the others in element content.

Any application whose option list is built from data rather than literals, using an options_ method, a build_options method or a DBIC model, allows attacker-influenced text in an option value or label that can embed JavaScript in rendered pages. Attribute values built from data, such as through element_attr, are affected the same way.

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.
