An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-2459 in the wild and no public exploit code.\n\nAffected product: Hitachi Energy Relion REB500. 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-2026-2459/ (Markdown: https://insights.sbomify.com/CVE-2026-2459/index.md)","id":"CVE-2026-2459","markdown":"https://insights.sbomify.com/CVE-2026-2459/index.md","name":"CVE-2026-2459","record":{"aliases":["GHSA-8hm4-jmvc-cfg9"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Relion REB500","requires_auth":"high_privilege","summary":"Authenticated Installer users can access and modify unauthorized directories in Hitachi Energy Relion REB500 devices.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Hitachi Energy","cpe":[{"product":"reb500_firmware","vendor":"hitachienergy"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-267","name":"Privilege Defined With Unsafe Actions"}],"description":"A vulnerability exists in REB500 for an authenticated user with Installer role to access and alter the contents of directories that the role is not authorized to do so.","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":"Missing authorization in Relion REB500","id":"CVE-2026-2459","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in Relion REB500","id":"CVE-2026-2460"},"packages":[],"prev":{"headline":"Unauthorized channel enumeration in private teams after member removal","id":"CVE-2026-2458"},"products":["Relion REB500"],"published":"2026-02-24","related":[{"cvss_score":7.6,"headline":"Missing authorization in Relion REB500","id":"CVE-2026-2460","kev_date_added":null,"published":"2026-02-24"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-02-28","vendors":["Hitachi Energy"]},"summary":"Authenticated Installer users can access and modify unauthorized directories in Hitachi Energy Relion REB500 devices.","url":"https://insights.sbomify.com/CVE-2026-2459/"}
