Summary
epa4all-client: TLS Certificate Validation Disabled in Production
Details

Impact

An attacker on the network path between the ePA service and the Konnektor can present any TLS certificate (self-signed, expired, wrong CN) and intercept all SOAP traffic. This includes patient identifiers (KVNR), SMC-B card operations (authentication, signing), document content, and credential exchanges.

Patches

#36

Workarounds

Use the library directly instead of the REST wrapper.
