It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-52748 in the wild and no public exploit code.\n\nAffected product: Kaon AR2140. 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-2026-52748/ (Markdown: https://insights.sbomify.com/CVE-2026-52748/index.md)","id":"CVE-2026-52748","markdown":"https://insights.sbomify.com/CVE-2026-52748/index.md","name":"CVE-2026-52748","record":{"aliases":["GHSA-vcfv-29fp-vc3c"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Kaon AR2140X router","requires_auth":"none","summary":"Unauthenticated attackers can trigger configuration backups, causing denial of service and potentially exposing encrypted configuration data.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERT-PL","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"The Kaon AR2140X router contains a vulnerability where the backup functionality is accessible without authentication.
