CVE-2026-54700	Medium	2026-10-13	No exploit published	No public exploit	ConnectBot SSH Client Library is written in Kotlin with Kaitai Struct and KStateMachine. Prior to 0.3.1, the SSH protocol parser trusts attacker-controlled inner byte lengths and element counts without verifying that they fit in the containing packet. A malicious or compromised SSH server can return a small malformed packet whose oversized declarations cause the Kaitai Struct Java runtime to attempt excessive allocation or repeated parsing before detecting truncated input. The general transport path requires a client connection but no authentication or optional feature; malformed SSH-agent messages additionally require SSH agent forwarding. The issue can raise an uncaught OutOfMemoryError and terminate the application process, with no demonstrated confidentiality or integrity impact. This issue is fixed in version 0.3.1.
CVE-2026-54697	Medium	2026-10-13	No exploit published	No public exploit	ConnectBot SSH Client Library is written in Kotlin with Kaitai Struct and KStateMachine. Prior to 0.3.1, DerReader.readLength() accepts excessive long-form DER length octets, accumulates them into an Int, and primitive readers allocate arrays without checking the declared size against the remaining input. An application or user that loads an attacker-provided private-key file through SshClient.authenticatePublicKey(), SshKeys.decodePemPrivateKey(), SshSigning.sign(), or SshSigning.getPublicKey() can trigger integer wraparound, excessive allocation, or an uncaught OutOfMemoryError. SSH server host keys and agent-forwarding messages do not use this application-supplied private-key input path. No usable weakened key and no confidentiality or integrity impact have been demonstrated. This issue is fixed in version 0.3.1.
CVE-2026-58624	Medium	2026-07-20	No exploit published	No public exploit	Improper input validation in sshd-git in Apache MINA SSHD. Apache MINA SSHD is a Java library for client-side and server-side SSH. Component org.apache.sshd:sshd-git provides though its GitPgmCommandFactory a way to configure an Apache MINA SSHD server such that SSH clients can remotely execute git commands via the JGit library on git repositories stored on the server. This GitPgmCommandFactory allowed a user authenticated via SSH to run any JGit command available, including commands that could write files at arbitrary places such as git archive with the --output option. Affected are SSH servers implemented with Apache MINA SSHD and using the GitPgmCommandFactory. If the GitPgmCommandFactory is not configured on the server, the server is not affected. It is recommended to upgrade affected servers to Apache MINA SSHD 2.19.0 or 3.0.0-M5, which fix this issue. The issue is fixed by restricting the available commands to a small whitelist of uncritical commands (such as git log). git archive is also allowed, but its --output argument is ignored and the archive is always sent through the SSH channel to the client.
CVE-2026-56624	High	2026-07-20	No exploit published	No public exploit	Improper certificate validation in Apache MINA SSHD (server-side). Apache MINA SSHD is a Java library for client-side and server-side SSH. Server-side OpenSSH user certificate validation during user authentication in an Apache MINA SSHD server did not check for the unsupported force-command or verify-required options that could be embedded in the certificate, nor did it validate these options. As a result it was possible that a user could authenticate with such a certificate that included a force-command option but still was able to execute other commands. What other command exactly would be available to the user depends on the implementation of the server. This issue is fixed in Apache MINA SSHD 2.19.0 and 3.0.0-M5. Applications are advised to upgrade to these versions. The fix rejects OpenSSH user certificates that include these options, since Apache MINA SSHD implements neither force-command nor sk-*-cert-v01@openssh.com user certificates (which are the only ones for which verify-required would make sense).
CVE-2026-56623	High	2026-07-20	Protected by Waratek	No public exploit	Path traversal on Windows in Apache MINA SSHD component sshd-git. Apache MINA SSHD is a Java library for client-side and server-side SSH. A git server implemented with Apache MINA SSHD component sshd-git and running on Windows could allow an authenticated remote user access to git repositories outside of the configured server-side root directory. The path validation applied for CVE-2026-48827 in Apache MINA SSHD 2.18.0 and 3.0.0-M4 was partly ineffective for Servers running on Windows. Applications are affected if they use org.apache.sshd:sshd-git to implement a git server and run on Windows. Applications not using sshd-git or not running on Windows are not affected. Users are advised to upgrade affected applications to Apache MINA SSHD 2.19.0, which fixes the issue. The issue also is present in the pre-release milestones 3.0.0-M1 to 3.0.0-M4 for a new upcoming new major version 3.0.0. Again, applications are affected only if they use sshd-git and run on Windows. Upgrade affected applications to 3.0.0-M5.
CVE-2026-56452	High	2026-07-20	Protected by Waratek	No public exploit	Path traversal in the sshd-scp component of Apache MINA SSHD. Apache MINA SSHD is a Java library for client-side and server-side SSH. The implementation of receiving files or directories via SCP did not validate filenames in SCP "C" or "D" commands. A malicious sender could send filenames containing paths, resulting in files to be written in attacker-controlled places. The issue affects only * applications that use no longer supported Apache MINA SSHD versions < 2.0.0 and use the SCP functions to receive files, * or applications using sshd-scp in Apache MINA SSHD >= 2.0.0 to receive files. Applications using Apache MINA SSHD >= 2.0.0 not using sshd-scp are not affected. The issue is fixed in Apache MINA 2.19.0 and 3.0.0-M5. Affected applications are advised to upgrade to these versions.
CVE-2026-48827	High	2026-06-01	Protected by Waratek	No public exploit	Path traversal vulnerability in Apache MINA SSHD bundle sshd-git. Lack of path validation in git-upload-pack, git-receive-pack, and other git operations allows users authenticated over SSH access to git repositories outside the configured git server root directory. Applications are affected if they use org.apache.sshd:sshd-git. Applications not using sshd-git are not affected. Users are advised to upgrade affected applications to Apche MINA SSHD 2.18.0, which fixes the issue. The issue also is present in the pre-release milestones 3.0.0-M1 to 3.0.0-M3 for a new upcoming new major version 3.0.0. Again, applications are affected only if they use sshd-git. Upgrade affected applications to 3.0.0-M4. We would like to point out that a professional git server should not rely solely on file system layout and permissions, but should implement additional security controls to govern access to git repositories and operations allowed on particular git repositories.
CVE-2025-32754	Critical	2025-04-10	No exploit published	No public exploit	In jenkins/ssh-agent Docker images 6.11.1 and earlier, SSH host keys are generated on image creation for images based on Debian, causing all containers based on images of the same version use the same SSH host keys, allowing attackers able to insert themselves into the network path between the SSH client (typically the Jenkins controller) and SSH build agent to impersonate the latter.
CVE-2024-41909	Medium	2024-08-12	No exploit published	No public exploit	Like many other SSH implementations, Apache MINA SSHD suffered from the issue that is more widely known as CVE-2023-48795. An attacker that can intercept traffic between client and server could drop certain packets from the stream, potentially causing client and server to consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack The mitigations to prevent this type of attack were implemented in Apache MINA SSHD 2.12.0, both client and server side. Users are recommended to upgrade to at least this version. Note that both the client and the server implementation must have mitigations applied against this issue, otherwise the connection may still be affected.
CVE-2023-41939	High	2023-09-06	No exploit published	No public exploit	Jenkins SSH2 Easy Plugin 1.4 and earlier does not verify that permissions configured to be granted are enabled, potentially allowing users formerly granted (typically optional permissions, like Overall/Manage) to access functionality they're no longer entitled to.
CVE-2023-35887	Medium	2023-07-10	Protected by Waratek	No public exploit	Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Software Foundation Apache MINA. In SFTP servers implemented using Apache MINA SSHD that use a RootedFileSystem, logged users may be able to discover "exists/does not exist" information about items outside the rooted tree via paths including parent navigation ("..") beyond the root, or involving symlinks. This issue affects Apache MINA: from 1.0 before 2.10. Users are recommended to upgrade to 2.10
CVE-2022-30959	Medium	2022-05-17	No exploit published	No public exploit	A missing permission check in Jenkins SSH Plugin 2.6.1 and earlier allows attackers with Overall/Read permission to connect to an attacker-specified SSH server using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

CVE-2022-23114	Low	2022-01-12	No exploit published	No public exploit	Jenkins Publish Over SSH Plugin 1.22 and earlier stores password unencrypted in its global configuration file on the Jenkins controller where it can be viewed by users with access to the Jenkins controller file system.
CVE-2022-23113	Medium	2022-01-12	Protected by Waratek	No public exploit	Jenkins Publish Over SSH Plugin 1.22 and earlier performs a validation of the file name specifying whether it is present or not, resulting in a path traversal vulnerability allowing attackers with Item/Configure permission to discover the name of the Jenkins controller files.
CVE-2022-23112	Medium	2022-01-12	No exploit published	No public exploit	A missing permission check in Jenkins Publish Over SSH Plugin 1.22 and earlier allows attackers with Overall/Read access to connect to an attacker-specified SSH server using attacker-specified credentials.

CVE-2022-23110	Medium	2022-01-12	No exploit published	No public exploit	Jenkins Publish Over SSH Plugin 1.22 and earlier does not escape the SSH server name, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Overall/Administer permission.
CVE-2022-20620	Medium	2022-01-12	No exploit published	No public exploit	Missing permission checks in Jenkins SSH Agent Plugin 1.23 and earlier allows attackers with Overall/Read access to enumerate credentials IDs of credentials stored in Jenkins.
CVE-2021-30129	Medium	2021-07-12	No exploit published	No public exploit	A vulnerability in sshd-core of Apache Mina SSHD allows an attacker to overflow the server causing an OutOfMemory error. This issue affects the SFTP and port forwarding features of Apache Mina SSHD version 2.0.0 and later versions. It was addressed in Apache Mina SSHD 2.7.0
CVE-2018-1999036	Medium	2018-08-01	No exploit published	No public exploit	An exposure of sensitive information vulnerability exists in Jenkins SSH Agent Plugin 1.15 and earlier in SSHAgentStepExecution.java that exposes the SSH private key password to users with permission to read the build log.
CVE-2017-2648	Medium	2018-07-27	No exploit published	No public exploit	It was found that jenkins-ssh-slaves-plugin before version 1.15 did not perform host key verification, thereby enabling Man-in-the-Middle attacks.
