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-2026-76471 in the wild and no public exploit code.\n\nAffected product: Cisco NX-OS Software. 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-2026-76471/ (Markdown: https://insights.sbomify.com/CVE-2026-76471/index.md)","id":"CVE-2026-76471","markdown":"https://insights.sbomify.com/CVE-2026-76471/index.md","name":"CVE-2026-76471","record":{"aliases":["GHSA-cw8g-p542-fwjp"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Cisco NX-OS","requires_auth":"none","summary":"Unauthenticated remote attackers can execute arbitrary code with root privileges or cause denial of service on Cisco NX-OS devices via crafted NX-API requests.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to execute arbitrary code with root privileges or cause a denial of service (DoS) condition on an affected device.\u0026nbsp;\r\n\r\nThe vulnerability is due to insufficient input validation of data that is sent to the NX-API.
