# OpenEMR: claim file endpoint leaks patient clinical documents to billing users

Link for people: https://infrastack.ai/live/CVE-2026-126417 (this .md is for agents)

OpenEMR before 8.5.0 has an access control flaw in get_claim_file.php: with location=tmp it serves any file in the shared temporary directory without checking it is a claim. A user with billing or EOB write access can download the most recently validated patient's full C-CDA clinical document.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the OpenEMR version in the installation; versions below `8.5.0` are listed as affected.
- Look for the file get_claim_file.php in the OpenEMR web tree and confirm whether it is reachable by users with acct/eob or acct/bill access.

## Fix

- OpenEMR versions before `8.5.0` are affected; move to `8.5.0` or later.

## From the sources

OpenEMR before 8.5.0 contains an access control flaw in get_claim_file.php: with location=tmp, it serves any file in the shared temporary directory without verifying the file is a claim for the caller. Users with acct/eob or acct/bill write access can request key=ccda.xml to download the most recently validated patient's complete C-CDA clinical document.
