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-2026-101956 in the wild and no public exploit code.\n\nAffected product: Juniper Networks Junos OS. 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-2026-101956/ (Markdown: https://insights.sbomify.com/CVE-2026-101956/index.md)","id":"CVE-2026-101956","markdown":"https://insights.sbomify.com/CVE-2026-101956/index.md","name":"CVE-2026-101956","record":{"aliases":["GHSA-x4rx-8qrw-pqpw"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"Junos OS","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary root commands on Junos OS devices if the J-Web interface is enabled.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:L","version":"4.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"An Improper Authentication vulnerability in the J-Web web management component of Juniper Networks Junos OS allows an unauthenticated remote attacker to execute arbitrary Junos commands with root privileges via the exposed J-Web web interface.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Junos OS: Unauthorized root command execution when J-Web is enabled","id":"CVE-2026-101956","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Junos OS and Junos OS Evolved: A remote BGP peer causes an rpd crash when long-lived graceful restart (LLGR) is used","id":"CVE-2026-101957"},"packages":[],"prev":{"headline":"Junos OS: SRX Series: Malformed DNS packet causes service disruption when UTM Anti-Spam SBL is used","id":"CVE-2026-101955"},"products":["Junos OS"],"published":"2026-10-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Juniper Networks"]},"summary":"Unauthenticated attackers can execute arbitrary root commands on Junos OS devices if the J-Web interface is enabled.","url":"https://insights.sbomify.com/CVE-2026-101956/"}
