What is CVE-2026-25220?

CVE-2026-25220 is a medium-severity missing authorization vulnerability in Open-Emr Openemr, published on 25 Feb 2026. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

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.
