CVE-2026-24849: OpenEMR Arbitrary File Read Vulnerability

Noroxi assessment

Priority: Monitor (action score 27/100)

Public proof-of-concept code exists (Exploit-DB, GitHub); there is no record of exploitation in the wild.
Probability of exploitation in the next 30 days: 2.1% (FIRST EPSS); higher than 82.3% of all records.
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.
No fixed version is recorded, but the references include a patch (commit or PR) link.
Severity is disputed: the assigning authority (CNA) scores it 10.0, NVD 6.5.

Low priority for now. See the fix and affected versions sections below.

Primary sources: NVD · CVE.org · FIRST EPSS

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 7.0.4, the `disposeDocument()` method in `EtherFaxActions.php` allows authenticated users to read arbitrary files from the server filesystem. Any authenticated user (regardless of privilege level) can exploit this vulnerability to read sensitive files. Version 7.0.4 patches the issue.

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.
