Description

epa4all-client: Unauthenticated REST API for Patient Record Writes

Impact

Any network-reachable caller can write arbitrary documents to any patient's electronic health record accessible by the institution's SMC-B card. In a misconfigured deployment (e.g., following the production Docker example in the README), this is exploitable from the local network without credentials.

Patches

#43

Workarounds

Use network policies or proxies to enforce service-to-service authentication via e.g. mTLS.

run the service in an isolated network namespace e.g. as Kubernetes sidecar

service-mesh with corresponding policies
