{"apiVersion":"1.0","identifier":"CVE-2026-50576","description":"ePA 3.x Integration implements the authorization workflow and writes Medical Information Objects to Germany-s electronic patient record. Prior to 1.3.0, ePA 3.x Integration does not neutralize CRLF characters in values used by app/vau/VAUProtokoll.py to construct VAU inner HTTP requests. The build_inner_header function interpolates the uri, host, accept_type, content_type, content_length, USER_AGENT, and insurant_id values into request lines and headers, including x-useragent and x-insurantid. An authenticated attacker who controls a value can inject additional headers into the inner request. Depending on ePA server handling, an injected x-insurantid header can expose another patient-s records, and injected Authorization headers can bypass the intended authentication or authorization context. Session-derived USER_AGENT input can also poison requests across the session. This issue is fixed in version 1.3.0.","publishedAt":"2026-08-18T17:16:58","lastModifiedAt":"2026-08-18T20:17:16","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-50576","cvssScore":6.8,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","epssProbability":0.00302,"riskScore":0.7,"affectedProduct":"ePA 3.x Integration","affectedVersions":"<1.3.0","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-50576","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-50576","en":"https://www.redsauce.net/en/cves/CVE-2026-50576","fr":"https://www.redsauce.net/fr/cves/CVE-2026-50576","pt":"https://www.redsauce.net/pt/cves/CVE-2026-50576","de":"https://www.redsauce.net/de/cves/CVE-2026-50576","sk":"https://www.redsauce.net/sk/cves/CVE-2026-50576","el":"https://www.redsauce.net/el/cves/CVE-2026-50576"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-50576"}}
