CVE-2026-124450: OpenEMR before 8.3.0 Arbitrary File Read/Write via disposeDocument
Noroxi assessment
Priority: Monitor (action score 37/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.48% (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 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.
