Archer MR600, published on 10 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-2026-76653 in the wild and no public exploit code.\n\nAffected product: TP-Link Systems Inc. Archer MR600. 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-2026-76653/ (Markdown: https://insights.sbomify.com/CVE-2026-76653/index.md)","id":"CVE-2026-76653","markdown":"https://insights.sbomify.com/CVE-2026-76653/index.md","name":"CVE-2026-76653","record":{"aliases":["GHSA-4rwx-9hrf-jj43"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"TP-Link router","requires_auth":"none","summary":"Remote attackers can access and modify VPN settings on TP-Link routers without authentication due to missing access controls.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TPLink","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-126","name":"Buffer Over-read"}],"description":"A missing\nauthentication vulnerability in the VPN configuration management has been\nidentified in Archer MR600 (v2, v3 \u0026 v5) and TL-MR6400 v8 due to improper access control; a remote unauthenticated attacker\nmay be able to access and modify VPN configuration information without valid\ncredentials.\n\nSuccessful\nexploitation may allow a remote unauthenticated attacker to disclose and modify\nVPN configuration information.","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 Authentication in VPN Configuration Management in TP-Link TL-MR6400 and Archer MR600","id":"CVE-2026-76653","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Subpath symlinking on Windows nodes permits NTLM coercion","id":"CVE-2026-76654"},"packages":[],"prev":{"headline":"Authenticated Directory Traversal Vulnerability in File Upload Functionality in TP-Link TL-MR6400 and Archer MR600","id":"CVE-2026-76652"},"products":["Archer MR600","TL-MR6400 v8"],"published":"2026-09-10","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":"2026-09-10","vendors":["TP-Link Systems Inc."]},"summary":"Remote attackers can access and modify VPN settings on TP-Link routers without authentication due to missing access controls.","url":"https://insights.sbomify.com/CVE-2026-76653/"}
