  <https://www.openssh.org/txt/release-10.3>.

CVE-2026-35385: A file downloaded by scp may be installed setuid or setgid, an
                outcome contrary to some users' expectations, if the download is

                (preserve mode).
CVE-2026-35386: Command execution can occur via shell metacharacters in a
                username within a command line. This requires a scenario where
                the username on the command line is untrusted, and also requires
                a non-default configurations of % in ssh_config.
CVE-2026-35387: OpenSSH can use unintended ECDSA algorithms. Listing of any
                ECDSA algorithm in PubkeyAcceptedAlgorithms or
                HostbasedAcceptedAlgorithms is misinterpreted to mean all ECDSA
                algorithms.
CVE-2026-35388: OpenSSH before omits connection multiplexing confirmation for
                proxy-mode multiplexing sessions.
CVE-2026-35414: OpenSSH mishandles the authorized_keys principals option in
                uncommon scenarios involving a principals list in conjunction
                with a Certificate Authority that makes certain use of comma
                characters.
