CVE-2026-114555 · Severity: info · Published 2026-10-30

The Data Field module for Drupal allows administrators to create custom fields with multiple values. An attacker with file upload permissions can inject malicious code through unescaped filenames in file links, potentially compromising other users who view the content. The vulnerability requires authenticated access to the file upload feature, limiting its exposure.

## Technical details

The file_uri formatter in Data Field fails to properly escape filenames when rendering links to uploaded files, allowing stored cross-site scripting (XSS). An attacker with the permission to upload files into a Data Field file subfield can craft a malicious filename that executes JavaScript when the link is rendered. This is a stored XSS vulnerability affecting all versions prior to 2.0.14.
