{"id":"CVE-2026-57850","summary":"RustDesk Missing Session Scope Enforcement Allows Out-of-Scope Control Message Injection","details":"RustDesk before 1.4.9 does not enforce a session's authorized connection scope on the server side, so a peer granted a limited session type (FileTransfer, PortForward, ViewCamera, or Terminal) can send control messages and login options reserved for a full Remote session. An authenticated remote peer can exploit this missing scope check to act outside its granted scope, injecting out-of-scope control messages to observe and control the host beyond the permissions it was given.","modified":"2026-08-13T03:52:00.831776013Z","published":"2026-07-10T19:53:21.336Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57850.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57850.json"},{"type":"ADVISORY","url":"https://github.com/rustdesk/rustdesk/releases/tag/1.4.9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57850"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/rustdesk-missing-session-scope-enforcement-allows-out-of-scope-control-message-injection"},{"type":"FIX","url":"https://github.com/rustdesk/rustdesk/commit/493b14ba78abc3dfb33f109c7f93c1c95a1dabc4"},{"type":"FIX","url":"https://github.com/rustdesk/rustdesk/pull/15469"},{"type":"PACKAGE","url":"https://github.com/rustdesk/rustdesk"},{"type":"ARTICLE","url":"https://github.com/sn0x-sharma/CVE-2026-57850"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rustdesk/rustdesk","events":[{"introduced":"0"},{"fixed":"6c578292e8ebbbec708b76986ba8c4bc7c509747"},{"fixed":"493b14ba78abc3dfb33f109c7f93c1c95a1dabc4"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.4.9"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["1.4.8","1.4.7","1.4.6","nightly","1.4.5","1.4.4","1.4.3","1.4.2","1.4.1","1.4.0","1.3.9","1.3.8","1.3.7","1.3.6","1.3.5","1.3.4","1.3.3","1.3.2","1.3.1","1.3.0","1.2.7","1.2.6","1.2.5","fdroid-version","1.2.4","1.2.3-2","1.2.3-1","1.2.3","1.2.2","1.2.1","1.2.0","1.1.9","1.1.8","1.1.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-57850.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N"}]}
