It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-1838 in the wild and no public exploit code.\n\nAffected product: HUAWEI Mate 30 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-2020-1838/ (Markdown: https://insights.sbomify.com/CVE-2020-1838/index.md)","id":"CVE-2020-1838","markdown":"https://insights.sbomify.com/CVE-2020-1838/index.md","name":"CVE-2020-1838","record":{"aliases":["GHSA-7334-vj9v-548q"],"analysis":{"component_type":"mobile_application","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Huawei Mate 30 Pro","requires_auth":"none","summary":"Attackers can bypass facial authentication on Huawei Mate 30 Pro devices by crafting invalid credentials, gaining unauthorized access to the device.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"mate_30_pro_firmware","vendor":"huawei"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"HUAWEI Mate 30 Pro with versions earlier than 10.1.0.150(C00E136R5P3) have is an improper authentication vulnerability.
