Description
BottleCRM through 1.14.5 contains a server-side template injection vulnerability in the send_email Celery task, which compiles the user-supplied AccountEmail message_body with django.template.Template(). Authenticated organization members can submit template tags through POST /api/accounts/<id>/create_mail/ to disclose the rendering context and loaded Python modules, or block the shared Celery worker with nested loops.
