Authentication flow hijacking in Gematik Authenticator (versions <4.16.0) enables remote attackers to impersonate victim users through malicious deep links. This affects a critical healthcare identity provider used across Germany's digital health infrastructure. The vulnerability requires user interaction (clicking a crafted link) but requires no attacker authentication (CVSS AV:N/PR:N/UI:R), enabling complete account takeover with high confidentiality and integrity impact. EPSS data not available; no public exploit identified at time of analysis, though the attack vector's social engineering component makes weaponization straightforward once technical details become public.
Remote code execution in gematik Authenticator (macOS) versions 4.12.0 through 4.15.x enables malicious file-triggered command injection when victims open crafted documents. This CWE-78 OS command injection flaw requires no authentication but depends on user interaction (CVSS:3.1/AV:L/AC:L/PR:N/UI:R). No public exploit identified at time of analysis, though EPSS data not available. The authenticator serves German digital health applications, making this a high-impact target for healthcare sector attacks.
The reference validator is a tool to perform advanced validation of FHIR resources for TI applications and interoperability standards. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
