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-2026-0647 in the wild and no public exploit code.\n\nAffected product: Rockwell Automation FLEX I/O EtherNet/IP Adapters. 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-2026-0647/ (Markdown: https://insights.sbomify.com/CVE-2026-0647/index.md)","id":"CVE-2026-0647","markdown":"https://insights.sbomify.com/CVE-2026-0647/index.md","name":"CVE-2026-0647","record":{"aliases":["GHSA-vhq6-x73f-hjjx"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["account_takeover","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial I/O adapter","requires_auth":"none","summary":"Unauthenticated attackers can change the web interface password on Rockwell FLEX I/O adapters, leading to account takeover and loss of availability.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Rockwell","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"An improper authentication security issue exists within the 1794-AENTR adapter's embedded web server.
