An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-4478 exists.\n\nAffected product: YI Home Camera. 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-2026-4478/ (Markdown: https://insights.sbomify.com/CVE-2026-4478/index.md)","id":"CVE-2026-4478","markdown":"https://insights.sbomify.com/CVE-2026-4478/index.md","name":"CVE-2026-4478","record":{"aliases":["GHSA-mp64-rm5r-c35p"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Yi Home Camera","requires_auth":"none","summary":"Attackers can bypass firmware signature verification to install malicious firmware on Yi Home Cameras, potentially gaining remote code execution.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"},{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"A vulnerability was identified in Yi Technology YI Home Camera 2 2.1.1_20171024151200. This impacts an unknown function of the file home/web/ipc of the component HTTP Firmware Update Handler. The manipulation leads to improper verification of cryptographic signature. The attack is possible to be carried out remotely. The complexity of an attack is rather high. The exploitability is said to be difficult. The exploit is publicly available and might be used.
