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-2026-51640 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2026-51640/ (Markdown: https://insights.sbomify.com/CVE-2026-51640/index.md)","id":"CVE-2026-51640","markdown":"https://insights.sbomify.com/CVE-2026-51640/index.md","name":"CVE-2026-51640","record":{"aliases":["GHSA-wmfp-mp4j-23gh"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"TOTOLINK mesh router","requires_auth":"none","summary":"Unauthenticated attackers can access mesh neighbor information via a crafted POST request due to incorrect access control in the TOTOLINK T6 router.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Incorrect access control in the getMeshNeighborTable function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to obtain mesh neighbor information via sending a crafted POST request to /cgi-bin/cstecgi.cgi.","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":"Missing authorization in n/a","id":"CVE-2026-51640","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Information disclosure in n/a","id":"CVE-2026-51641"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2026-51639"},"products":["n/a"],"published":"2026-08-28","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":"2026-09-01","vendors":["n/a"]},"summary":"Unauthenticated attackers can access mesh neighbor information via a crafted POST request due to incorrect access control in the TOTOLINK T6 router.","url":"https://insights.sbomify.com/CVE-2026-51640/"}
