SOCFortress CoPilot focuses on providing a single pane of glass for all your security operations needs. Prior to 0.1.76, in the reported deployment, case-report templates uploaded by `customer_user`, the lowest-privilege portal role, are later executed by non-sandboxed Jinja2 engines when an admin or analyst generates a report. The `/case-report-template/upload` route in `backend/app/incidents/routes/db_operations.py` validates only the filename-derived MIME type, not the template content. Templates share a global store without customer_code scoping, and `customer_user` can also list, download and delete them, allowing an attacker to replace a legitimate default template under the same name. In `backend/app/incidents/services/reports.py`, `render_document_with_context` uses `DocxTemplate` without a sandbox; in `backend/app/incidents/services/reports_pdf.py`, `render_html_template` uses a non-sandboxed `Environment` without autoescaping. Normal privileged requests to `POST /api/incidents/report/generate-report-docx` or `/generate-report-pdf` therefore evaluate attacker-controlled Jinja expressions as Python on the backend. The reported deployment executes commands as root, exposing all tenants' incident and SIEM data and stored connector credentials. The HTML/PDF wkhtmltopdf renderer additionally permits local-file reads and requests to internal services. This issue is fixed in version 0.1.76.
