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.
AnalysisAI
Improper certificate validation in epa4all's TLS handshake with the ePA backend allows a man-in-the-middle attacker who can intercept the connection to decrypt and manipulate all inner HTTP traffic, including patient consent decisions, medication data, and authorization tokens, and to inject arbitrary requests
