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-2026-59999 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-2026-59999/ (Markdown: https://insights.sbomify.com/CVE-2026-59999/index.md)","id":"CVE-2026-59999","markdown":"https://insights.sbomify.com/CVE-2026-59999/index.md","name":"CVE-2026-59999","record":{"aliases":["ALPINE-CVE-2026-59999","AZL-92051","BELL-CVE-2026-59999","CLSA-2026-1785317563","DEBIAN-CVE-2026-59999","ECHO-eb7c-7431-a44d","GHSA-gcm2-x6hm-q4h3","JLSEC-2026-1323","ROOT-OS-DEBIAN-11-CVE-2026-59999","ROOT-OS-DEBIAN-12-CVE-2026-59999","UBUNTU-CVE-2026-59999"],"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":"Attackers can bypass DisableForwarding restrictions to enable tunneling when PermitTunnel is enabled, undermining intended security controls.","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":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-348","name":"Use of Less Trusted Source"}],"description":"In sshd in OpenSSH before 10.4, DisableForwarding=yes was supposed to take precedence over PermitTunnel=yes, but did not.","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-2026-59999","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":"Denial of service in OpenSSH","id":"CVE-2026-60000"},"packages":[],"prev":{"headline":"Security feature bypass in OpenSSH","id":"CVE-2026-59998"},"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":"Attackers can bypass DisableForwarding restrictions to enable tunneling when PermitTunnel is enabled, undermining intended security controls.","url":"https://insights.sbomify.com/CVE-2026-59999/"}
