CAN-2-USB, published on 14 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-82793 in the wild and no public exploit code.\n\nAffected product: Contec Co., Ltd. CAN-2-USB. 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-2026-82793/ (Markdown: https://insights.sbomify.com/CVE-2026-82793/index.md)","id":"CVE-2026-82793","markdown":"https://insights.sbomify.com/CVE-2026-82793/index.md","name":"CVE-2026-82793","record":{"aliases":["GHSA-463x-vp7x-ppgq"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"CAN converter unit","requires_auth":"high_privilege","summary":"Remote authenticated attackers can upload malicious files to Contec CAN converter units to execute arbitrary code.","user_interaction":"not_required","vuln_class":"file_upload"},"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-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Unrestricted upload of file with dangerous type issue exists in Contec CAN 2.0B Communication Wireless LAN / USB Converter Unit.
