CVE-2026-126760: Drupal Data Field cross-site scripting in autocomplete

CVE-2026-126760 · Severity: info · Published 2026-11-11

The Data Field module for Drupal provides a widget for storing and searching structured data with multiple sub-fields. Its autocomplete search feature fails to properly escape field values before displaying them as suggestions, allowing attackers with entity editing permissions to inject malicious scripts that execute in other users' browsers. An attacker would need permission to edit entities using the Data Field and have the Search - autocomplete widget enabled on that field.

Technical details

The vulnerability is a stored cross-site scripting (XSS) flaw in the autocomplete endpoint of the Data Field module. The endpoint returns field values as suggestion labels without sufficient HTML escaping, allowing an authenticated attacker to inject JavaScript. The vulnerability requires two preconditions: the attacker must have permission to edit an entity carrying a Data Field field, and the Search - autocomplete widget must be configured on that field.
