## Affected

- sassanix Warracker: from 1.0.0, fixed in 1.0.4

## Description

Warracker before 1.0.4 contains a missing authorization vulnerability in its Paperless-ngx integration that allows an authenticated, non-administrative user to bypass document ownership restrictions by searching for and linking another user's private document ID to a warranty they own using the `other` document type. Attackers can exploit insufficient authorization checks in the `paperless_search_and_link()` and `serve_paperless_document()` route handlers in file_routes.py to retrieve and disclose private documents belonging to another user via the shared Paperless-ngx API credential, resulting in unauthorized read access and confidentiality loss.

## FAQ

### What does this mean?

Any signed-in non-administrative user who owns a warranty can read private Paperless-ngx documents that the Warracker service account can read, bypassing the owner-only restriction. This is a loss of confidentiality.

### Am I affected, and how do I check?

Warracker versions 1.0.0 up to but not including 1.0.4 with the Paperless-ngx integration enabled. Check the installed Warracker version and whether the Paperless-ngx integration is turned on, and confirm that the configured API token can read the target document.

### Is it being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.
