CVE-2026-124446: OpenEMR before 8.3.0 Arbitrary File Read and Write via FaxSMS disposeDocument

HighCVSS 8.7 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 34/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.34% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: openemr openemr 8.3.0.

Low priority for now. Upgrade to openemr openemr 8.3.0 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
