Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-5548 in the wild and no public exploit code.\n\nAffected product: Tenda Ac10 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-2026-5548/ (Markdown: https://insights.sbomify.com/CVE-2026-5548/index.md)","id":"CVE-2026-5548","markdown":"https://insights.sbomify.com/CVE-2026-5548/index.md","name":"CVE-2026-5548","record":{"aliases":["GHSA-mf8f-5hfr-3cfm"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Tenda AC10 router","requires_auth":"low_privilege","summary":"A remote attacker can trigger a stack-based buffer overflow in the Tenda AC10 router's httpd service via the sys.userpass argument, potentially leading to code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"ac10_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:X","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 vulnerability was found in Tenda AC10 16.03.10.10_multi_TDE01.
