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-2026-78239 in the wild and no public exploit code.\n\nAffected product: Xiiaozet LK100W. 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-2026-78239/ (Markdown: https://insights.sbomify.com/CVE-2026-78239/index.md)","id":"CVE-2026-78239","markdown":"https://insights.sbomify.com/CVE-2026-78239/index.md","name":"CVE-2026-78239","record":{"aliases":["GHSA-38f6-3gv7-32xr"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Xiiaozet LK100W","requires_auth":"none","summary":"Remote attackers can invoke critical management functions without authentication to enable restricted administrative services on the device.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Xiiaozet LK100W exposes a critical management function that can be \ninvoked without authentication, allowing a remote attacker to enable \nadministrative services that should be restricted.
