CVE-2026-58056
CVE-2026-58056 updated by NVD
Summary
RustDesk gates incoming control messages on per-capability flags rather than on the session's authorized connection type, and a file-transfer session does not clear those flags. A peer holding only a valid FileTransfer authorization can inject keyboard and mouse input and reach the unguarded screenshot and display-capture handlers, acting outside its granted scope.
