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-2026-41020/ (Markdown: https://insights.sbomify.com/CVE-2026-41020/index.md)","id":"CVE-2026-41020","markdown":"https://insights.sbomify.com/CVE-2026-41020/index.md","name":"CVE-2026-41020","record":{"aliases":["GHSA-4r7w-hmfv-2648"],"analysis":null,"analysis_generated_by":null,"assigner":"Eaton","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-294","name":"Authentication Bypass by Capture-replay"}],"description":"Eaton easyE4 uses a static nonce during authentication, which could allow an unauthenticated attacker with access to captured authentication traffic to replay a valid authentication exchange and gain unauthorized access to the device.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Eaton easyE4 uses a static nonce during authentication, which could allow an unauthenticated attacker with access to captured authentication","id":"CVE-2026-41020","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Eaton easyE4 uses an insufficiently strong password policy.","id":"CVE-2026-41021"},"packages":[],"prev":{"headline":"Apache Airflow Providers Elasticsearch: Elasticsearch task-log handler leaks credentials embedded in the host URL","id":"CVE-2026-41018"},"products":["easyE4"],"published":"2026-10-27","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-27","vendors":["Eaton"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-41020/"}
