DescriptionGitHub Advisory

InvenTree is an Open Source Inventory Management System. From 0.16.0 to before 1.2.7, any authenticated InvenTree user can create a valid API token attributed to any other user in the system - including administrators and superusers - by supplying the target's user ID in the user field of a POST /api/user/tokens/ request. The returned token is immediately usable for full API authentication as the target user, from any network location, with no further interaction required. This vulnerability is fixed in 1.2.7 and 1.3.0.

AnalysisAI

Authentication bypass in InvenTree open source inventory management system allows any authenticated user to generate API tokens for arbitrary users, including administrators, enabling complete account takeover. Affected versions 0.16.0 through 1.2.6 permit low-privileged users to forge API credentials by manipulating the user field in POST requests to /api/user/tokens/. Resulting tokens provide full API access from any network location without requiring victim interaction. No public exploit identified at time of analysis.

Technical ContextAI

Broken access control in token generation endpoint fails to validate user field parameter against authenticated session identity (CWE-639: Authorization Bypass Through User-Controlled Key). API endpoint accepts arbitrary user_id values in POST body, creating valid JWT or session tokens for targeted accounts without authorization checks, enabling horizontal and vertical privilege escalation through forged credential issuance.

RemediationAI

Vendor-released patch: upgrade immediately to InvenTree version 1.2.7 or 1.3.0, which enforce proper authorization checks preventing token generation for non-owned user accounts. No workaround exists for unpatched installations; applying the security update is mandatory. Organizations unable to upgrade immediately should restrict API access to trusted networks only and audit all API tokens created since version 0.16.0 deployment for unauthorized credential issuance. Revoke any tokens created by users other than the token owner.
