|---|---|---|---|---|
| CVE-2005-2798 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2026-04-16 | N/A |
| sshd in OpenSSH before 4.2, when GSSAPIDelegateCredentials is enabled, allows GSSAPI credentials to be delegated to clients who log in using non-GSSAPI methods, which could cause those credentials to be exposed to untrusted users or hosts. | ||||
| CVE-2003-1562 | 1 Openbsd | 1 Openssh | 2026-04-16 | N/A |
| sshd in OpenSSH 3.6.1p2 and earlier, when PermitRootLogin is disabled and using PAM keyboard-interactive authentication, does not insert a delay after a root login attempt with the correct password, which makes it easier for remote attackers to use timing differences to determine if the password step of a multi-step authentication is successful, a different vulnerability than CVE-2003-0190. | ||||
| CVE-2006-0225 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2026-04-16 | N/A |
| scp in OpenSSH 4.2p1 allows attackers to execute arbitrary commands via filenames that contain shell metacharacters or spaces, which are expanded twice. | ||||
| CVE-2025-61984 | 1 Openbsd | 1 Openssh | 2026-04-15 | 3.6 Low |
| ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted sources are the command line and %-sequence expansion of a configuration file. (A configuration file that provides a complete literal username is not categorized as an untrusted source.) | ||||
| CVE-2026-35414 | 1 Openbsd | 1 Openssh | 2026-04-10 | 4.2 Medium |
| OpenSSH before 10.3 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. | ||||
| CVE-2026-35386 | 1 Openbsd | 1 Openssh | 2026-04-07 | 3.6 Low |
| In OpenSSH before 10.3, 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 | 1 Openbsd | 1 Openssh | 2026-04-07 | 3.1 Low |
| OpenSSH before 10.3 can use unintended ECDSA algorithms. Listing of any ECDSA algorithm in PubkeyAcceptedAlgorithms or HostbasedAcceptedAlgorithms is misinterpreted to mean all ECDSA algorithms. | ||||
| CVE-2026-35388 | 1 Openbsd | 1 Openssh | 2026-04-07 | 2.5 Low |
| OpenSSH before 10.3 omits connection multiplexing confirmation for proxy-mode multiplexing sessions. | ||||
| CVE-2026-35385 | 1 Openbsd | 1 Openssh | 2026-04-03 | 7.5 High |
| In OpenSSH before 10.3, a file downloaded by scp may be installed setuid or setgid, an outcome contrary to some users' expectations, if the download is performed as root with -O (legacy scp protocol) and without -p (preserve mode). | ||||
| CVE-2020-14145 | 3 Netapp, Openbsd, Redhat | 11 Active Iq Unified Manager, Aff A700s, Aff A700s Firmware and 8 more | 2025-12-18 | 5.9 Medium |
| The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected. | ||||
| CVE-2019-6111 | 10 Apache, Canonical, Debian and 7 more | 27 Mina Sshd, Ubuntu Linux, Debian Linux and 24 more | 2025-12-18 | 5.9 Medium |
| An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file). | ||||
| CVE-2019-6110 | 4 Netapp, Openbsd, Siemens and 1 more | 9 Element Software, Ontap Select Deploy, Storage Automation Store and 6 more | 2025-12-18 | 6.8 Medium |
| In OpenSSH 7.9, due to accepting and displaying arbitrary stderr output from the server, a malicious server (or Man-in-The-Middle attacker) can manipulate the client output, for example to use ANSI control codes to hide additional files being transferred. | ||||
| CVE-2018-15919 | 2 Netapp, Openbsd | 7 Cloud Backup, Cn1610, Cn1610 Firmware and 4 more | 2025-12-18 | 5.3 Medium |
| Remotely observable behaviour in auth-gss2.c in OpenSSH through 7.8 could be used by remote attackers to detect existence of users on a target system when GSS2 is in use. NOTE: the discoverer states 'We understand that the OpenSSH developers do not want to treat such a username enumeration (or "oracle") as a vulnerability.' | ||||
| CVE-2018-20685 | 9 Canonical, Debian, Fujitsu and 6 more | 30 Ubuntu Linux, Debian Linux, M10-1 and 27 more | 2025-12-17 | 5.3 Medium |
| In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side. | ||||
| CVE-2018-15473 | 7 Canonical, Debian, Netapp and 4 more | 25 Ubuntu Linux, Debian Linux, Aff Baseboard Management Controller and 22 more | 2025-12-17 | 5.9 Medium |
| OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c. | ||||
| CVE-2023-51767 | 3 Fedoraproject, Openbsd, Redhat | 3 Fedora, Openssh, Enterprise Linux | 2025-11-18 | 7 High |
| OpenSSH through 10.0, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges. NOTE: this is disputed by the Supplier, who states "we do not consider it to be the application's responsibility to defend against platform architectural weaknesses." | ||||
| CVE-2020-15778 | 4 Broadcom, Netapp, Openbsd and 1 more | 11 Fabric Operating System, A700s, A700s Firmware and 8 more | 2025-07-28 | 7.8 High |
| scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows." | ||||
| CVE-2025-32728 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2025-05-22 | 4.3 Medium |
| In sshd in OpenSSH before 10.0, the DisableForwarding directive does not adhere to the documentation stating that it disables X11 and agent forwarding. | ||||
| CVE-2019-16905 | 3 Netapp, Openbsd, Siemens | 7 Cloud Backup, Steelstore Cloud Integrated Storage, Openssh and 4 more | 2025-04-23 | 7.8 High |
| OpenSSH 7.7 through 7.9 and 8.x before 8.1, when compiled with an experimental key type, has a pre-authentication integer overflow if a client or server is configured to use a crafted XMSS key. This leads to memory corruption and local code execution because of an error in the XMSS key parsing algorithm. NOTE: the XMSS implementation is considered experimental in all released OpenSSH versions, and there is no supported way to enable it when building portable OpenSSH. | ||||
| CVE-2017-15906 | 5 Debian, Netapp, Openbsd and 2 more | 23 Debian Linux, Active Iq Unified Manager, Cloud Backup and 20 more | 2025-04-20 | 5.3 Medium |
| The process_open function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files. | ||||
