CVE ID :CVE-2026-71239
Published : Aug. 5, 2026, 11:16 a.m. | 1 hour, 39 minutes ago
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. An authenticated user with mass-mail message edit rights can inject Django template syntax ({{ }} / {% %}) that executes at render time, enabling disclosure of other users' data and password hashes via request context variables, CSRF token forgery, and inclusion of arbitrary registered templates.
Severity: 8.1 | HIGH
