{"id":"CVE-2026-110835","summary":"FreeRDP 3.0.0 before 3.32.0 HTTP Header Injection via Proxy Routing Token","details":"FreeRDP 3.0.0 before 3.32.0 allows HTTP header injection in its proxy because a lone LF in the target portion of a routing token (Cookie: msts=) is not rejected and is written by http_proxy_connect into the CONNECT request line and Host header. A remote unauthenticated RDP client connecting to a proxy using FixedTarget=false and an upstream HTTP proxy can alter HTTP request/header framing at that upstream proxy.","aliases":["GHSA-87v8-2gwr-ww9j"],"modified":"2026-10-15T10:47:32.074862729Z","published":"2026-10-14T22:52:10.348Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110835.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-93"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110835.json"},{"type":"ADVISORY","url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-87v8-2gwr-ww9j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110835"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/freerdp-3.0.0-before-3.32.0-http-header-injection-via-proxy-routing-token"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/freerdp/freerdp","events":[{"introduced":"a34fa7c49d2a39aa49ace1d7bea9656912d8c7cb"},{"fixed":"d27a4f7c1c63b62a5e60e5d939ad116cfb58ffc1"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"3.0.0"},{"fixed":"3.32.0"}]}}],"versions":["3.5.1","3.5.0","3.4.0","3.3.0","3.2.0","3.1.0","3.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110835.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:L/SA:N"}]}
