AI risk analysis

Summary: The flaw allows untrusted user input to be directly rendered in email templates, leading to potential template injection attacks.
Exploitability: Exploitation is relatively easy as it requires user-controlled input to be embedded directly into email templates without sanitization.
Blast radius: If exploited, this could lead to unauthorized access to email content and potentially compromise user data.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to the latest version of DjangoCRM that includes the necessary sanitization for user-controlled inputs.

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.
