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: Yes. Attackers have exploited CVE-2021-30657 in the wild since at least 3 Nov 2021.\n\nAffected product: Apple Mac Os X. 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-2021-30657/ (Markdown: https://insights.sbomify.com/CVE-2021-30657/index.md)","id":"CVE-2021-30657","markdown":"https://insights.sbomify.com/CVE-2021-30657/index.md","name":"CVE-2021-30657","record":{"aliases":["GHSA-4f6h-9vp6-5p6r"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"macOS","requires_auth":"none","summary":"A logic flaw in macOS allows malicious applications to bypass Gatekeeper security checks, potentially enabling unauthorized code execution.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apple","cpe":[{"product":"mac_os_x","vendor":"apple"},{"product":"macos","vendor":"apple"}],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","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-862","name":"Missing Authorization"}],"description":"A logic issue was addressed with improved state management.
