CVE-2026-126433: OpenEMR before 8.5.0 Improper Authorization via dispense_drug.php

MediumCVSS 6.0 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 24/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • 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 8.5.0.

Low priority for now. Upgrade to openemr openemr 8.5.0 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

OpenEMR before 8.5.0 contains an improper authorization vulnerability in interface/drugs/dispense_drug.php, which checks only for admin/drugs view permission instead of write permission before dispensing medication. Authenticated users with read-only drug administration access can send GET requests with drug_id, quantity, fee, and encounter parameters to create false dispensing records and decrement inventory.
