CVE-2026-40075: OpenMRS Core is an open source electronic medical record system platform

This week

HIGH 7.5REMOTEUPGRADE

CVE-2026-40075 is a high-severity flaw (CVSS 7.5) affecting openmrs. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

OpenMRS Core is an open source electronic medical record system platform. In versions 2.7.8 and earlier and versions 2.8.0 through 2.8.5, the `/openmrs/moduleResources/{moduleid}` endpoint is vulnerable to a path traversal attack. The ModuleResourcesServlet constructs a filesystem path from user-controlled input without performing path boundary validation — the getFile() method concatenates the user-supplied path into an absolute filesystem path

openmrs openmrs UPGRADE

Affected: <= 2.7.8 · >= 2.8.0 and <= 2.8.5

Fixed in: newer than 2.8.5

Safe to downgrade to: a release before 2.8.0

1. Check installed version

apt-cache policy openmrs || rpm -q openmrs || openmrs --version

2. UPGRADE to newer than 2.8.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade openmrs

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade openmrs

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 2.8.0 (Debian / Ubuntu)

apt-cache madison openmrs sudo apt install openmrs=<VERSION_BEFORE_2.8.0> sudo apt-mark hold openmrs

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list openmrs sudo dnf downgrade openmrs-<VERSION_BEFORE_2.8.0> sudo dnf versionlock add openmrs

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
