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-2026-126329 in the wild and no public exploit code.\nExposure: Only installations with a non-default setting turned on are exposed.\n\nAffected product: Docker Sandboxes. 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-2026-126329/ (Markdown: https://insights.sbomify.com/CVE-2026-126329/index.md)","id":"CVE-2026-126329","markdown":"https://insights.sbomify.com/CVE-2026-126329/index.md","name":"CVE-2026-126329","record":{"aliases":["GHSA-w92q-8xxw-h4r9"],"analysis":{"component_type":"container_or_infrastructure","exploitable_when_present":false,"fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"container sandbox","requires_auth":"low_privilege","requires_specific_call":false,"summary":"Local users can substitute sockets and config in untrusted state directories to run commands as root when Docker Sandboxes runs as root.","user_interaction":"not_required","vuln_class":"privilege_escalation","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"Docker","cpe":[],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-282","name":"Improper Ownership Management"}],"description":"Docker Sandboxes reuses existing state and configuration directories without verifying their ownership.
