An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-40061 in the wild and no public exploit code.\n\nAffected product: F5 Big-Ip Domain Name System. 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-2026-40061/ (Markdown: https://insights.sbomify.com/CVE-2026-40061/index.md)","id":"CVE-2026-40061","markdown":"https://insights.sbomify.com/CVE-2026-40061/index.md","name":"CVE-2026-40061","record":{"aliases":["GHSA-rpj4-762v-f8r2"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"F5 BIG-IP DNS","requires_auth":"high_privilege","summary":"Authenticated administrators can execute arbitrary system commands with higher privileges in BIG-IP DNS, potentially crossing security boundaries in Appliance mode.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"f5","cpe":[{"product":"big-ip_domain_name_system","vendor":"f5"}],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"When BIG-IP DNS is provisioned, a vulnerability exists in an undisclosed iControl REST and BIG-IP TMOS Shell (tmsh) command that may allow an authenticated attacker with the Resource Administrator or Administrator role to execute arbitrary system commands with higher privileges.
