TL-WR940N v6, published on 29 Jul 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-12935 in the wild and no public exploit code.\n\nAffected product: TP-Link Systems Inc. TL-WR940N v6. 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-2026-12935/ (Markdown: https://insights.sbomify.com/CVE-2026-12935/index.md)","id":"CVE-2026-12935","markdown":"https://insights.sbomify.com/CVE-2026-12935/index.md","name":"CVE-2026-12935","record":{"aliases":["GHSA-4j6v-4j5m-vgpq"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"TP-Link router","requires_auth":"none","summary":"An unauthenticated attacker can trigger a stack-based buffer overflow in the RTSP conntrack module, leading to remote code execution or denial of service on the router.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TPLink","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"The\nTL-WR940N v6 router contains a vulnerability in its RTSP connection tracking\nmodule that can lead to a stack-based buffer overflow.
