TL-MR6400 v7.0, published on 21 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-2026-17251 in the wild and no public exploit code.\n\nAffected product: TP-Link Systems Inc. TL-MR6400 v7.0. 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-2026-17251/ (Markdown: https://insights.sbomify.com/CVE-2026-17251/index.md)","id":"CVE-2026-17251","markdown":"https://insights.sbomify.com/CVE-2026-17251/index.md","name":"CVE-2026-17251","record":{"aliases":["GHSA-cfmx-mjrq-52xj"],"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 router","requires_auth":"none","summary":"An unauthenticated remote attacker can crash the HTTP service on TP-Link TL-MR6400 v7 routers by sending a malformed session cookie header.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TPLink","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"A NULL\npointer dereference vulnerability exists in the HTTP request parsing\nfunctionality of \nTL-MR6400 v7.
