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-2026-5527 in the wild and no public exploit code.\n\nAffected product: Tenda 4G03 Pro. 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-2026-5527/ (Markdown: https://insights.sbomify.com/CVE-2026-5527/index.md)","id":"CVE-2026-5527","markdown":"https://insights.sbomify.com/CVE-2026-5527/index.md","name":"CVE-2026-5527","record":{"aliases":["GHSA-pgjq-fxv2-9p7v"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"4G router","requires_auth":"none","summary":"Attackers can exploit a hard-coded ECDSA private key in Tenda 4G03 Pro routers to bypass security controls and access sensitive data.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"4g03_pro_firmware","vendor":"tenda"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-321","name":"Use of Hard-coded Cryptographic Key"},{"id":"CWE-320","name":null}],"description":"A weakness has been identified in Tenda 4G03 Pro 1.0/1.0re/01.bin/04.03.01.53.
