Archer AX55 v4, published on 3 Sep 2026. 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-2026-18167 in the wild and no public exploit code.\n\nAffected product: TP-Link Systems Inc. Archer AX55 v4. 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-2026-18167/ (Markdown: https://insights.sbomify.com/CVE-2026-18167/index.md)","id":"CVE-2026-18167","markdown":"https://insights.sbomify.com/CVE-2026-18167/index.md","name":"CVE-2026-18167","record":{"aliases":["GHSA-6hpq-jhqf-p8v4"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Wi-Fi router","requires_auth":"none","summary":"A stack-based buffer overflow in the EasyMesh module allows LAN attackers to crash the daemon or potentially execute code when Mesh mode is enabled.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TPLink","cpe":[],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A\nstack-based buffer overflow vulnerability exists in the EasyMesh module of\nTP-Link Archer AX55 v4.
