Detailsinfo

A vulnerability has been found in InvenTree up to 1.2.5 and classified as critical. This vulnerability affects the function encode_svg_image/asset/uploaded_image of the file src/backend/InvenTree/report/templatetags/report.py of the component Template Handler. The manipulation with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

InvenTree is an Open Source Inventory Management System. Prior to version 1.2.6, a path traversal vulnerability in the report template engine allows a staff-level user to read arbitrary files from the server filesystem via crafted template tags. Affected functions: `encode_svg_image()`, `asset()`, and `uploaded_image()` in `src/backend/InvenTree/report/templatetags/report.py`. This requires staff access (to upload / edit templates with maliciously crafted tags). If the InvenTree installation is configured with high access privileges on the host system, this path traversal may allow file access outside of the InvenTree source directory. This issue is patched in version 1.2.6, and 1.3.0 (or above). Users should update to the patched versions. No known workarounds are available.

The advisory is available at github.com. This vulnerability was named CVE-2026-33531 since 03/20/2026. The exploitation appears to be easy. The attack can be initiated remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1505 by the MITRE ATT&CK project.

Upgrading to version 1.2.6 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
