Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-20126 in the wild and no public exploit code.\n\nAffected product: Cisco Catalyst Sd-Wan Manager. 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-2026-20126/ (Markdown: https://insights.sbomify.com/CVE-2026-20126/index.md)","id":"CVE-2026-20126","markdown":"https://insights.sbomify.com/CVE-2026-20126/index.md","name":"CVE-2026-20126","record":{"aliases":["GHSA-mjw4-rp5q-2h7w"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco SD-WAN Manager","requires_auth":"low_privilege","summary":"An authenticated local attacker can exploit insufficient REST API authentication to gain root privileges on the underlying operating system.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"catalyst_sd-wan_manager","vendor":"cisco"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-648","name":"Incorrect Use of Privileged APIs"}],"description":"A vulnerability in Cisco Catalyst SD-WAN Manager could allow an authenticated, local attacker with low privileges to gain root privileges on the underlying operating system.\r\n\r\nThis vulnerability is due to an insufficient user authentication mechanism in the REST API.
