Lifecycle Timeline
4Description
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.
Analysis
OpenEMR versions prior to 8.0.0 allow any authenticated user to view all internal messages and notes from other users by exploiting insufficient authorization checks on the Message Center's `show_all` parameter. The vulnerability exists because the application does not verify administrator privileges before returning the complete message list, enabling unauthorized disclosure of sensitive medical communications. …
