Archer A6 v4, published on 7 Aug 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-2026-9031 in the wild and no public exploit code.\n\nAffected product: TP-Link Systems Inc. Archer A6 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-2026-9031/ (Markdown: https://insights.sbomify.com/CVE-2026-9031/index.md)","id":"CVE-2026-9031","markdown":"https://insights.sbomify.com/CVE-2026-9031/index.md","name":"CVE-2026-9031","record":{"aliases":["GHSA-7f4x-hjwm-h5px"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"TP-Link Archer A6","requires_auth":"high_privilege","summary":"An authenticated attacker can crash the HTTPD service on TP-Link Archer A6 routers via insufficient input validation, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TPLink","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"An input validation\nvulnerability exists in the HTTP-WRITEOEM handler due to insufficient validation\nof user-supplied data before it is processed by internal flash-write handling\nlogic.\n\nSuccessful\nexploitation may cause httpd process or device to crash, resulting in loss of access\nto the web interface and a denial-of-service condition.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Authenticated Denial-of-Service in HTTPD Service in TP-Link Archer A6","id":"CVE-2026-9031","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Unauthenticated Onboarding Connect NULL Pointer Dereference Denial of Service Vulnerability in TP-Link Tapo C120 \u0026 C200","id":"CVE-2026-9032"},"packages":[],"prev":{"headline":"Authenticated Denial-of-Service in HTTPD Service in TP-Link Archer A6","id":"CVE-2026-9030"},"products":["Archer A6 v4"],"published":"2026-08-07","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-10","vendors":["TP-Link Systems Inc."]},"summary":"An authenticated attacker can crash the HTTPD service on TP-Link Archer A6 routers via insufficient input validation, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2026-9031/"}
