TL-WR841N v14, published on 28 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-2026-76649 in the wild and no public exploit code.\n\nAffected product: TP-Link System Inc. TL-WR841N v14. 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-2026-76649/ (Markdown: https://insights.sbomify.com/CVE-2026-76649/index.md)","id":"CVE-2026-76649","markdown":"https://insights.sbomify.com/CVE-2026-76649/index.md","name":"CVE-2026-76649","record":{"aliases":["GHSA-2cvh-668x-j624"],"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":"A pre-authentication null pointer dereference in the UPnP service allows attackers to cause a denial-of-service condition on TP-Link TL-WR841N routers.","user_interaction":"not_required","vuln_class":"null_dereference"},"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:N/VI:N/VA:L/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 TL-WR841N v14 in the UPnP service when processing SOAP action requests.
