# OpenEMR: FaxSMS module lets logged-in users read and overwrite server files

Link for people: https://infrastack.ai/live/CVE-2026-124446 (this .md is for agents)

OpenEMR's FaxSMS module fails to sanitize the file_path parameter in its RCFaxClient and SignalWireClient disposeDocument functions, which is a path traversal flaw. An authenticated low-privilege user can download arbitrary files, including sqlconf.php with database credentials, or overwrite web-server-writable files.

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

## How to check

- Check the OpenEMR version in the deployed installation; versions before `8.3.0` are affected.
- Confirm whether the FaxSMS module is enabled and uses RCFaxClient or SignalWireClient.

## Fix

- OpenEMR: move to `8.3.0` or later.

- [advisory] Vendor advisory: github.com https://github.com/openemr/openemr/security/advisories/GHSA-x2vr-jgg8-c57c
- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/openemr-before-8.3.0-arbitrary-file-read-and-write-via-faxsms-disposedocument

## From the sources

OpenEMR before 8.3.0 contains a path traversal vulnerability in the FaxSMS module's RCFaxClient and SignalWireClient disposeDocument functions that allows authenticated low-privilege users to read and overwrite arbitrary files via the unsanitized file_path parameter. Attackers can request action=download to retrieve cleartext files like sqlconf.php database credentials and keys, or use action=setup to overwrite web-server-writable files with ciphertext.
