Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-20220 in the wild and no public exploit code.\n\nAffected product: Cisco Crosswork Network Change Automation. 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-2026-20220/ (Markdown: https://insights.sbomify.com/CVE-2026-20220/index.md)","id":"CVE-2026-20220","markdown":"https://insights.sbomify.com/CVE-2026-20220/index.md","name":"CVE-2026-20220","record":{"aliases":["GHSA-x9r3-4p88-q7rc"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Crosswork Network Controller","requires_auth":"low_privilege","summary":"Authenticated attackers with template write permissions can execute arbitrary commands via crafted requests in the web management interface.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"crosswork_network_controller","vendor":"cisco"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"A vulnerability in the web-based management interface of Cisco Crosswork Network Controller could allow an\u0026nbsp;authenticated, remote attacker to execute arbitrary commands on an affected device.\r\n\r\nThis vulnerability is due to insufficient input validation in the configuration\u0026nbsp;template engine of the web-based management interface.
