Description

OpenEMR before 8.3.0 contains a broken access control and path traversal vulnerability in the fax/sms module disposeDocument action via an unvalidated file_path parameter. Authenticated low-privilege users can read sqlconf.php to recover database credentials and write arbitrary files as the web user, enabling remote code execution.

Detection & mitigation playbook

Vulnerability

  1. Detect

    Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

  2. Remediation status

    The records we use list no fixed release for CVE-2026-124450. Check the upstream advisory for a patched version, and apply the exposure-reduction steps below in the meantime.

  3. Mitigate without a patch

    Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
