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-2026-75943 in the wild and no public exploit code.\n\nAffected product: Arista Networks EOS. 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-2026-75943/ (Markdown: https://insights.sbomify.com/CVE-2026-75943/index.md)","id":"CVE-2026-75943","markdown":"https://insights.sbomify.com/CVE-2026-75943/index.md","name":"CVE-2026-75943","record":{"aliases":["GHSA-w63v-3gq5-cj26"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Arista EOS","requires_auth":"low_privilege","summary":"Authenticated users can bypass ACL enforcement during brief removal windows, allowing unauthorized traffic passage on Arista EOS devices.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Arista","cpe":[],"cvss":{"score":2.1,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-459","name":"Incomplete Cleanup"}],"description":"A brief (milliseconds to seconds) traffic leak may occur when an authenticated supplicant is removed, either via the clear dot1x host all CLI command or due to a supplicant timeout.
