CVE-2026-25745 Details
Description
OpenEMR is a free and open source electronic health records and medical practice management application. In versions up to and including 8.0.0, the message/note update endpoint (e.g. PUT or POST) updates by message/note ID only and does not verify that the message belongs to the current patient (or that the user is allowed to edit that patient’s notes). An authenticated user with notes permission can modify any patient’s messages by supplying another message ID. Commit 92a2ff9eaaa80674b3a934a6556e35e7aded5a41 contains a fix for the issue.
A vulnerability exists in OpenEMR versions through 8.0.0, allowing authenticated users with notes permission to modify any patient's messages. The issue arises because the message update endpoint only checks the message ID, without verifying if the message belongs to the current patient or if the user is authorized to edit that patient's notes. This flaw enables unauthorized alterations of patient communications, posing a risk to data integrity and compliance.
Users are advised to update to the latest version of OpenEMR, where this vulnerability has been addressed.
