Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-4960 exists.\n\nAffected product: Tenda Ac6 Firmware. 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-2026-4960/ (Markdown: https://insights.sbomify.com/CVE-2026-4960/index.md)","id":"CVE-2026-4960","markdown":"https://insights.sbomify.com/CVE-2026-4960/index.md","name":"CVE-2026-4960","record":{"aliases":["GHSA-mcgx-8v57-hq28"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Tenda AC6 router","requires_auth":"low_privilege","summary":"Remote attackers can trigger a stack-based buffer overflow in the Tenda AC6 router's WizardHandle function via crafted POST requests, potentially leading to code execution or service disruption.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"ac6_firmware","vendor":"tenda"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"},{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability was determined in Tenda AC6 15.03.05.16.
