Server code execution via staff-editable Jinja2 templates
Published Feb 25, 2026 · Updated Feb 25, 2026
Server-side template injection in InvenTree before 1.2.3 allows remote authenticated users to execute server code through its API. The STOCK_BATCH_CODE_TEMPLATE and PART_NAME_FORMAT settings feed staff-editable Jinja2 expressions into an unsandboxed renderer. A staff user must first save a malicious template; a later batch-code API request executes it in the requesting user's context, exposing data or running code.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
