An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-16812 and fix it if it is affected.\n\nWhat it is: CVE-2026-16812 is a critical command injection vulnerability in Arista Networks VeloCloud Orchestrator On-Prem, published on 27 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-16812 in the wild since at least 27 Jul 2026.\n\nAffected product: Arista Networks VeloCloud Orchestrator On-Prem. 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-2026-16812/ (Markdown: https://insights.sbomify.com/CVE-2026-16812/index.md)","id":"CVE-2026-16812","markdown":"https://insights.sbomify.com/CVE-2026-16812/index.md","name":"CVE-2026-16812","record":{"aliases":["GHSA-f2cp-q2qv-6563"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"VeloCloud Orchestrator","requires_auth":"none","summary":"Remote attackers can execute OS commands on VeloCloud Orchestrator hosts, compromising confidentiality, integrity, and availability.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Arista","cpe":[{"product":"velocloud_orchestrator","vendor":"arista"}],"cvss":{"score":10,"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:H/SI:H/SA:H/S:P","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"VeloCloud Orchestrator (VCO) on-prem has a security issue where this issue may allow a remote attacker to access privileged internal functionality and impact the VCO host.
