An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-24436 in the wild and no public exploit code.\n\nAffected product: Tenda W30e 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-2026-24436/ (Markdown: https://insights.sbomify.com/CVE-2026-24436/index.md)","id":"CVE-2026-24436","markdown":"https://insights.sbomify.com/CVE-2026-24436/index.md","name":"CVE-2026-24436","record":{"aliases":["GHSA-j73p-m2g8-wpgm"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Tenda W30E V2 router","requires_auth":"none","summary":"Attackers can brute-force administrative credentials on Tenda W30E V2 routers due to missing rate limiting, leading to potential account takeover.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"w30e_firmware","vendor":"tenda"}],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) do not enforce rate limiting or account lockout mechanisms on authentication endpoints.
