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-2026-5350 exists.\n\nAffected product: Trendnet TEW-657BRM. 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-2026-5350/ (Markdown: https://insights.sbomify.com/CVE-2026-5350/index.md)","id":"CVE-2026-5350","markdown":"https://insights.sbomify.com/CVE-2026-5350/index.md","name":"CVE-2026-5350","record":{"aliases":["GHSA-g7rc-cpg5-3v55"],"analysis":{"component_type":"network_device","fix_type":"end_of_life","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Trendnet wireless router","requires_auth":"low_privilege","summary":"Remote attackers can exploit a stack-based buffer overflow in the discontinued Trendnet TEW-657BRM router to execute arbitrary code.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"tew-657brm_firmware","vendor":"trendnet"}],"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-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A security flaw has been discovered in Trendnet TEW-657BRM 1.00.1.
