Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The epa4all-client Maven package, versions before 1.2.2, does not validate TLS certificates in production. An attacker on the network path between the ePA service and the Konnektor can present any certificate and intercept SOAP traffic, including patient identifiers and smart card operations. Upgrade to version 1.2.2. The source lists a workaround of calling the library directly instead of the REST wrapper.
