  "details": "In OpenSSH before 10.3, a file downloaded by scp may be installed setuid\nor setgid, an outcome contrary to some users' expectations, if the\ndownload is performed as root with -O (legacy scp protocol) and without\n-p (preserve mode). (CVE-2026-35385)\nIn OpenSSH before 10.3, command execution can occur via shell\nmetacharacters in a username within a command line. This requires a\nscenario where the username on the command line is untrusted, and also\nrequires a non-default configurations of % in ssh_config.\n(CVE-2026-35386)\nOpenSSH before 10.3 can use unintended ECDSA algorithms. Listing of any\nECDSA algorithm in PubkeyAcceptedAlgorithms or\nHostbasedAcceptedAlgorithms is misinterpreted to mean all ECDSA\nalgorithms. (CVE-2026-35387)\nOpenSSH before 10.3 omits connection multiplexing confirmation for\nproxy-mode multiplexing sessions. (CVE-2026-35388)\nOpenSSH before 10.3 mishandles the authorized_keys principals option in\nuncommon scenarios involving a principals list in conjunction with a\nCertificate Authority that makes certain use of comma characters.\n(CVE-2026-35414)\n",
