It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-47830 in the wild and no public exploit code.\n\nAffected product: Cloud Foundry Foundation bosh-windows-stemcell-builder. 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-2026-47830/ (Markdown: https://insights.sbomify.com/CVE-2026-47830/index.md)","id":"CVE-2026-47830","markdown":"https://insights.sbomify.com/CVE-2026-47830/index.md","name":"CVE-2026-47830","record":{"aliases":["GHSA-v8gm-j274-p577"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows stemcell builder","requires_auth":"low_privilege","summary":"Local attackers can overwrite executables to gain SYSTEM privileges on Windows stemcells, requiring an upgrade to the builder tool.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[],"description":"Incorrect Permission Assignment in BOSH.Utils.psm1 in BOSH-Ecosystem bosh-windows-stemcell-builder allows low-privilege authenticated users to overwrite C:\\bosh\\service_wrapper.exe or C:\\bosh\\bosh-agent.exe and gain NT AUTHORITY\\SYSTEM on the next service restart or reboot.
