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-2026-35362 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- uucore (crates.io): affected all versions; fixed in 0.6.0\n- uucore (crates.io): affected all versions; fixed in 0.6.0\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-2026-35362/ (Markdown: https://insights.sbomify.com/CVE-2026-35362/index.md)","id":"CVE-2026-35362","markdown":"https://insights.sbomify.com/CVE-2026-35362/index.md","name":"CVE-2026-35362","record":{"aliases":["DEBIAN-CVE-2026-35362","GHSA-w6xc-g9qj-vp32","UBUNTU-CVE-2026-35362"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["privilege_escalation","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"uutils coreutils","requires_auth":"low_privilege","summary":"Attackers can exploit symlink race conditions in directory traversal on non-Linux Unix systems due to missing TOCTOU protections in uutils coreutils.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"coreutils","vendor":"uutils"}],"cvss":{"score":3.6,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"The safe_traversal module in uutils coreutils, which provides protection against Time-of-Check to Time-of-Use (TOCTOU) symlink races using file-descriptor-relative syscalls, is incorrectly limited to Linux targets.
