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-2023-3747 in the wild and no public exploit code.\n\nAffected product: Cloudflare WARP Client. 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-2023-3747/ (Markdown: https://insights.sbomify.com/CVE-2023-3747/index.md)","id":"CVE-2023-3747","markdown":"https://insights.sbomify.com/CVE-2023-3747/index.md","name":"CVE-2023-3747","record":{"aliases":[],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Cloudflare WARP Client","requires_auth":"none","summary":"Local attackers can bypass WARP security enforcement by manipulating system time to extend override code validity, requiring administrator-created override codes.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cloudflare","cpe":[{"product":"warp","vendor":"cloudflare"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-565","name":"Reliance on Cookies without Validation and Integrity Checking"},{"id":"CWE-602","name":"Client-Side Enforcement of Server-Side Security"}],"description":"Zero Trust Administrators have the ability to disallow end users from disabling WARP on their devices.
