CVE-2026-71239Network attack vector

Authenticated data disclosure via mass-mail template injection

Published Aug 5, 2026 · Updated Aug 5, 2026

Server-side template injection in Django CRM 0 allows remote authenticated users to disclose data through crafted mass-mail fields. The massmail message preview and email creation paths pass EmlMessage subject and content values directly to Django Template(), so injected template syntax is evaluated during rendering. Mass-mail message edit rights are required; successful exploitation exposes request-context data and password hashes and permits CSRF-token forgery or inclusion of registered templates.
