WEX-G300, published on 28 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-86530 in the wild and no public exploit code.\n\nAffected product: BUFFALO INC. WEX-G300. 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-2026-86530/ (Markdown: https://insights.sbomify.com/CVE-2026-86530/index.md)","id":"CVE-2026-86530","markdown":"https://insights.sbomify.com/CVE-2026-86530/index.md","name":"CVE-2026-86530","record":{"aliases":["GHSA-j628-7w6r-937x"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Wi-Fi router","requires_auth":"high_privilege","summary":"An administrative user can execute arbitrary OS commands on BUFFALO Wi-Fi routers via crafted HTTP requests due to improper input handling.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"BUFFALO Wi-Fi products handle some web form input improperly to assemble command line strings internally.
