Description
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

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.oviva.telematik:epa4all-rest-service, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of com.oviva.telematik:epa4all-rest-service has shipped for CVE-2026-47672 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
