An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-8065 and fix it if it is affected.\n\nWhat it is: CVE-2026-8065 is a critical authentication bypass vulnerability in Hitachi Energy RTU500 series CMU firmware, published on 29 Sep 2026. 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-2026-8065 in the wild and no public exploit code.\n\nAffected product: Hitachi Energy RTU500 series CMU firmware. 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-2026-8065/ (Markdown: https://insights.sbomify.com/CVE-2026-8065/index.md)","id":"CVE-2026-8065","markdown":"https://insights.sbomify.com/CVE-2026-8065/index.md","name":"CVE-2026-8065","record":{"aliases":["GHSA-gg49-9mrv-ff3f"],"analysis":{"component_type":"ics_ot","fix_type":"end_of_life","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"RTU500 series firmware","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication to upload arbitrary firmware on Hitachi Energy RTU500 devices, compromising device integrity and availability.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Hitachi Energy","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"An authentication bypass vulnerability in the firmware update endpoint of Hitachi Energy RTU500 end-of-life versions allows an unauthenticated attacker to upload arbitrary firmware through a crafted POST request.
