What is CVE-2026-33531?

CVE-2026-33531 is a medium-severity path traversal vulnerability in InvenTree, published on 26 Mar 2026. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

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.

Weakness: CWE-89
