An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-14891 in the wild and no public exploit code.\n\nAffected product: HashiCorp Nomad. 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-2026-14891/ (Markdown: https://insights.sbomify.com/CVE-2026-14891/index.md)","id":"CVE-2026-14891","markdown":"https://insights.sbomify.com/CVE-2026-14891/index.md","name":"CVE-2026-14891","record":{"aliases":["GHSA-5c56-jfhx-4gcm","UBUNTU-CVE-2026-14891"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Nomad container orchestrator","requires_auth":"high_privilege","summary":"A job submitter can bypass volume restrictions to bind-mount host paths, enabling unauthorized reading and writing of host files.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HashiCorp","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"HashiCorp Nomad and Nomad Enterprise are vulnerable to a sandbox escape in the Docker task driver that may allow a job submitter to bind-mount a host path into a container even when volume bind mounts are disabled, potentially leading to reading and writing files on the host.
