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
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
