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-2026-35340 in the wild and no public exploit code.\n\nAffected product: Uutils coreutils. 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-2026-35340/ (Markdown: https://insights.sbomify.com/CVE-2026-35340/index.md)","id":"CVE-2026-35340","markdown":"https://insights.sbomify.com/CVE-2026-35340/index.md","name":"CVE-2026-35340","record":{"aliases":["DEBIAN-CVE-2026-35340","UBUNTU-CVE-2026-35340"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"uutils coreutils","requires_auth":"low_privilege","summary":"uutils coreutils chown/chgrp return success despite failures in recursive mode, potentially causing security misconfigurations in administrative scripts.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"coreutils","vendor":"uutils"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-253","name":"Incorrect Check of Function Return Value"}],"description":"A flaw in the ChownExecutor used by uutils coreutils chown and chgrp causes the utilities to return an incorrect exit code during recursive operations.
