Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-56624 in the wild and no public exploit code.\n\nAffected product: Apache MINA SSHD. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-56624/ (Markdown: https://insights.sbomify.com/CVE-2026-56624/index.md)","id":"CVE-2026-56624","markdown":"https://insights.sbomify.com/CVE-2026-56624/index.md","name":"CVE-2026-56624","record":{"aliases":["CLEANSTART-2026-BQ51036","CLEANSTART-2026-JH16561","CLEANSTART-2026-NF19276","DEBIAN-CVE-2026-56624","GHSA-j262-jh5j-p4fw","UBUNTU-CVE-2026-56624"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Java SSH library","requires_auth":"low_privilege","summary":"Attackers can bypass SSH certificate restrictions to execute unauthorized commands in applications using Apache MINA SSHD.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"mina_sshd","vendor":"apache"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"Improper certificate validation in Apache MINA SSHD (server-side). Apache MINA SSHD is a Java library for client-side and server-side SSH.\n\nServer-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.\n\nThis issue is fixed in Apache MINA SSHD 2.19.0 and 3.0.0-M5. Applications are advised to upgrade to these versions.\n\nThe 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).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Apache MINA SSHD: SSH certificate options lack validations","id":"CVE-2026-56624","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Fabric Data Warehouse Remote Code Execution Vulnerability","id":"CVE-2026-56642"},"packages":[],"prev":{"headline":"Apache MINA SSHD: Path traversal in org.apache.sshd:sshd-git on Windows","id":"CVE-2026-56623"},"products":["Apache MINA SSHD"],"published":"2026-07-20","related":[{"cvss_score":7.5,"headline":"Apache MINA SSHD: Path traversal in SCP file reception","id":"CVE-2026-56452","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":7.1,"headline":"Apache MINA SSHD: Path traversal in org.apache.sshd:sshd-git on Windows","id":"CVE-2026-56623","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":7.1,"headline":"Apache MINA SSHD: Path traversal in org.apache.sshd:sshd-git","id":"CVE-2026-48827","kev_date_added":null,"published":"2026-06-01"},{"cvss_score":5.9,"headline":"Apache MINA SSHD: integrity check bypass","id":"CVE-2024-41909","kev_date_added":null,"published":"2024-08-12"},{"cvss_score":5.9,"headline":"Path traversal in n/a","id":"CVE-2019-6111","kev_date_added":null,"published":"2019-01-31"},{"cvss_score":5.4,"headline":"Apache MINA SSHD: Remote execution of JGit commands can write files on the server","id":"CVE-2026-58624","kev_date_added":null,"published":"2026-07-20"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-23","vendors":["Apache Software Foundation"]},"summary":"Attackers can bypass SSH certificate restrictions to execute unauthorized commands in applications using Apache MINA SSHD.","url":"https://insights.sbomify.com/CVE-2026-56624/"}
