NVD description

DjangoCRM's massmail module renders user-controlled EmlMessage fields (subject, content) through Django's Template constructor with no sanitization, in at least three locations: message_previews.py builds an f-string embedding message.subject/message.content directly into a Template call; email_creators.py passes eml_message.subject directly as a template string to Template; and helpers.py contains the same f-string interpolation pattern.
