It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-106555 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-2026-106555/ (Markdown: https://insights.sbomify.com/CVE-2026-106555/index.md)","id":"CVE-2026-106555","markdown":"https://insights.sbomify.com/CVE-2026-106555/index.md","name":"CVE-2026-106555","record":{"aliases":["AZL-106709","BELL-CVE-2026-106555","DEBIAN-CVE-2026-106555","ECHO-a770-d49a-4681","GHSA-j45v-7hgc-xv9x","ROOT-OS-DEBIAN-12-CVE-2026-106555","ROOT-OS-DEBIAN-13-CVE-2026-106555","UBUNTU-CVE-2026-106555"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"OpenSSH server","requires_auth":"low_privilege","summary":"Attackers may bypass authentication in OpenSSH when GSSAPI is enabled due to state persistence across attempts.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"openssh","vendor":"openbsd"}],"cvss":{"score":2.2,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-669","name":"Incorrect Resource Transfer Between Spheres"}],"description":"In sshd in OpenSSH before 10.6, GSSAPIAuthentication authentication state can incorrectly be persisted across authentication attempts.","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":"Auth bypass in OpenSSH","id":"CVE-2026-106555","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"openbsd:openssh","products":["openbsd:openssh"],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Backstage: Configuration bypass in TechDocs mkdocs.yml sanitization","id":"CVE-2026-106556"},"packages":[],"prev":{"headline":"Auth bypass in OpenSSH","id":"CVE-2026-106553"},"products":["OpenSSH"],"published":"2026-10-06","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":"2026-10-09","vendors":["OpenBSD"]},"summary":"Attackers may bypass authentication in OpenSSH when GSSAPI is enabled due to state persistence across attempts.","url":"https://insights.sbomify.com/CVE-2026-106555/"}
