CVE-2026-25220: Open-EMR Openemr

Medium severity, CVSS 6.5. EPSS: 0.3% chance of exploitation in the next 30 days.

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, the Message Center accepts the URL parameter `show_all=yes` and passes it to `getPnotesByUser()`, which returns all internal messages (all users’ notes). The backend does not verify that the requesting user is an administrator before honoring `show_all=yes`. The "Show All" link is also visible to non-admin users. As a result, any authenticated user can view the entire internal message list by requesting `messages.php?show_all=yes`. Version 8.0.0 patches the issue.

Affected products

• Open-EMR Openemr: before 8.0.0 (fixed in 8.0.0)
