Summary
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.

Questions about CVE-2026-124446
Is CVE-2026-124446 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.Source: cve.now feed data
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.Source: github.com, vulncheck.com
Which versions are affected by CVE-2026-124446?
openemr: before 8.3.0.Source: cve.now feed data
Am I affected, and how do I check?
OpenEMR versions before 8.3.0 are affected, but only when the FaxSMS module's active vendor is RingCentral (fax or SMS) or SignalWire (fax). To check, look at the OpenEMR version and at which vendor is active in the FaxSMS module settings.Source: github.com, vulncheck.com
How do I fix CVE-2026-124446?
Upgrade OpenEMR to 8.3.0 or later, which contains the fix.Source: github.com, vulncheck.com
