An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-59998 in the wild and no public exploit code.\n\nAffected product: OpenSSH. 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-2026-59998/ (Markdown: https://insights.sbomify.com/CVE-2026-59998/index.md)","id":"CVE-2026-59998","markdown":"https://insights.sbomify.com/CVE-2026-59998/index.md","name":"CVE-2026-59998","record":{"aliases":["ALPINE-CVE-2026-59998","AZL-92184","BELL-CVE-2026-59998","CLSA-2026-1784280067","CLSA-2026-1784297006","DEBIAN-CVE-2026-59998","ECHO-f227-5da2-6774","GHSA-3j2g-cqmq-cjw9","JLSEC-2026-1322","ROOT-OS-DEBIAN-11-CVE-2026-59998","ROOT-OS-DEBIAN-12-CVE-2026-59998","ROOT-OS-DEBIAN-13-CVE-2026-59998","UBUNTU-CVE-2026-59998"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenSSH server","requires_auth":"none","summary":"OpenSSH server may bypass GSSAPI strict acceptance checks in Windows Active Directory environments, potentially weakening authentication security.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"openssh","vendor":"openbsd"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-573","name":"Improper Following of Specification by Caller"}],"description":"sshd in OpenSSH before 10.4 has an undocumented security-relevant behavior: GSSAPIStrictAcceptorCheck has no value if the server is in Windows Active Directory.","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":"Security feature bypass in OpenSSH","id":"CVE-2026-59998","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"openbsd:openssh","products":["openbsd:openssh"],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Security feature bypass in OpenSSH","id":"CVE-2026-59999"},"packages":[],"prev":{"headline":"Security feature bypass in OpenSSH","id":"CVE-2026-59997"},"products":["OpenSSH"],"published":"2026-07-08","related":[{"cvss_score":10,"headline":"Auth bypass in n/a","id":"CVE-2003-0786","kev_date_added":null,"published":"2003-09-25"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2003-0693","kev_date_added":null,"published":"2003-09-17"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2002-0640","kev_date_added":null,"published":"2003-04-02"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2001-0144","kev_date_added":null,"published":"2001-05-07"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2000-0999","kev_date_added":null,"published":"2000-11-29"},{"cvss_score":10,"headline":"Privilege escalation in n/a","id":"CVE-2000-0525","kev_date_added":null,"published":"2000-10-13"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2010-4478","kev_date_added":null,"published":"2010-12-06"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-07-08","vendors":["OpenBSD"]},"summary":"OpenSSH server may bypass GSSAPI strict acceptance checks in Windows Active Directory environments, potentially weakening authentication security.","url":"https://insights.sbomify.com/CVE-2026-59998/"}
