Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-20185 in the wild and no public exploit code.\n\nAffected product: Cisco Small Business Smart and Managed Switches. 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-2026-20185/ (Markdown: https://insights.sbomify.com/CVE-2026-20185/index.md)","id":"CVE-2026-20185","markdown":"https://insights.sbomify.com/CVE-2026-20185/index.md","name":"CVE-2026-20185","record":{"aliases":["GHSA-7rq4-mv4g-6vcp"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco managed switch","requires_auth":"low_privilege","summary":"An authenticated remote attacker can cause a denial of service on Cisco SG350 switches by sending a malicious SNMP request, requiring valid credentials.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A vulnerability in the Simple Network Management Protocol (SNMP) subsystem of\u0026nbsp;Cisco 350 Series Managed Switches (SG350) and Cisco 350X Series Stackable Managed Switches (SG350X)\u0026nbsp;firmware could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.\u0026nbsp;\r\n\r\nThis vulnerability is due to improper error handling when parsing response data for a specific SNMP request.
