• CVE-2026-73281 Low 3.5 In ssh-agent in OpenSSH before 10.5, some operations can occur remotely but were intended to occur only locally, including operations that add tokens or use keys. This is caused by misinteraction betw 0.2%

• CVE-2026-60000 Low 3.7 sshd in OpenSSH before 10.4 allows remote attackers to cause a denial of service (resource consumption from excessive authentication attempts) because MaxAuthTries was mishandled for GSSAPIAuthenticat 0.6%
• CVE-2026-59999 Medium 5.9 In sshd in OpenSSH before 10.4, DisableForwarding=yes was supposed to take precedence over PermitTunnel=yes, but did not. 0.2%

• CVE-2026-59997 Medium 4.2 internal-sftp in sshd in OpenSSH before 10.4 recognizes only the first 9 command-line arguments, which can be important if a later command-line argument would have helped to ensure the intended securi 0.2%
• CVE-2026-59996 Medium 4.2 scp in OpenSSH before 10.4 may place a file in the parent directory of an intended directory when the copy occurs between two remote destinations. 0.2%
• CVE-2026-59995 Medium 4.2 sftp in OpenSSH before 10.4 does not properly constrain the location of downloaded files when "sftp server:/path ." is used with an attacker-controlled server. 0.2%
