An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-16438 in the wild and no public exploit code.\n\nAffected product: Mitsubishi Electric Corporation AnalytiX. 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-2026-16438/ (Markdown: https://insights.sbomify.com/CVE-2026-16438/index.md)","id":"CVE-2026-16438","markdown":"https://insights.sbomify.com/CVE-2026-16438/index.md","name":"CVE-2026-16438","record":{"aliases":["GHSA-qcw9-8pcc-76g9"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["privilege_escalation","data_read","data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SCADA HMI software","requires_auth":"high_privilege","summary":"Attackers with admin access can bypass UAC to execute DCOM objects, leading to privilege escalation and data compromise in Mitsubishi SCADA systems.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mitsubishi","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-266","name":"Incorrect Privilege Assignment"}],"description":"Incorrect Privilege Assignment vulnerability in Mitsubishi Electric GENESIS64 versions 10.97.3 and prior, ICONICS Suite versions 10.97.3 and prior, Hyper Historian versions 10.97.3 and prior, AnalytiX versions 10.97.3 and prior, MobileHMI 10.97.3 and prior, MC Works64 all versions, Mitsubishi Electric Iconics Digital Solutions GENESIS64 versions 10.97.3 and prior, ICONICS Suite versions 10.97.3 and prior, Hyper Historian versions 10.97.3 and prior, AnalytiX versions 10.97.3 and prior, and MobileHMI 10.97.3 and prior allows an attacker who can log in using the same administrator account for the affected products to launch and operate DCOM objects locally or remotely.
