Routine
HIGH 8.1
CVE-2026-71239 is a high-severity flaw (CVSS 8.1) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- High severity
No fix is published yet: follow the downgrade or mitigation steps.
