Tenda F3, published on 23 Feb 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-2026-27513 in the wild and no public exploit code.\n\nAffected product: Shenzhen Tenda Technology Co., Ltd. Tenda F3. 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-2026-27513/ (Markdown: https://insights.sbomify.com/CVE-2026-27513/index.md)","id":"CVE-2026-27513","markdown":"https://insights.sbomify.com/CVE-2026-27513/index.md","name":"CVE-2026-27513","record":{"aliases":["GHSA-9hjg-4h75-mvc5"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Wireless Router","requires_auth":"none","summary":"An attacker can trick an authenticated administrator into submitting malicious requests to change router configuration via CSRF.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"f3_firmware","vendor":"tenda"}],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Shenzhen Tenda F3 Wireless Router firmware V12.01.01.55_multi contains a cross-site request forgery (CSRF) vulnerability in the web-based administrative interface.
