In epa4all, prior to version 2026-05-20, an attacker who can intercept the TLS connection between epa4all and the ePA backend can complete the VAU handshake with attacker-controlled keys and obtain the session encryption keys. All inner HTTP traffic (patient consent decisions, medication data, document operations, authorization tokens, and entitlement queries) becomes readable and modifiable. The attacker can also inject arbitrary requests through the hijacked channel. This issue has been patched in version 2026-05-20.
