An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-64119 in the wild and no public exploit code.\n\nAffected product: Nuvation Energy Battery Management System. 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-2025-64119/ (Markdown: https://insights.sbomify.com/CVE-2025-64119/index.md)","id":"CVE-2025-64119","markdown":"https://insights.sbomify.com/CVE-2025-64119/index.md","name":"CVE-2025-64119","record":{"aliases":["GHSA-757q-w8xv-793g"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Battery Management System","requires_auth":"none","summary":"Attackers can bypass authentication in Nuvation Energy Battery Management Systems, potentially gaining unauthorized access to critical industrial control functions.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Dragos","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/S:P/AU:Y","version":"4.0"},"cwes":[{"id":"CWE-603","name":"Use of Client-Side Authentication"}],"description":"A vulnerability in Nuvation Battery Management System allows Authentication Bypass.This issue affects Battery Management System: through 2.3.9.","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":"Nuvation Energy BMS Client-side Authentication","id":"CVE-2025-64119","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Nuvation Energy Multi-Stack Controller OS Command Injection","id":"CVE-2025-64120"},"packages":[],"prev":{"headline":"node-tar vulnerable to race condition leading to uninitialized memory exposure","id":"CVE-2025-64118"},"products":["Battery Management System"],"published":"2026-01-02","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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-01-05","vendors":["Nuvation Energy"]},"summary":"Attackers can bypass authentication in Nuvation Energy Battery Management Systems, potentially gaining unauthorized access to critical industrial control functions.","url":"https://insights.sbomify.com/CVE-2025-64119/"}
