Stored XSS via missing form-field attribute validation
Published Nov 20, 2024 · Updated Jun 2, 2026
Stored XSS in django CMS Attributes Fields before 4.0 allows remote authenticated users to run JavaScript in a victim's browser. AttributesFormField accepted dangerous attribute keys because form-field validation did not apply the model field's exclusions for event handlers, src, href, data, and action. Exploitation requires access to the django CMS admin interface and a victim to render the stored attributes, exposing browser-accessible data and actions.
