It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2023-4753 and fix it if it is affected.\n\nWhat it is: CVE-2023-4753 is a low-severity denial of service vulnerability in Openatom Openharmony, published on 21 Sep 2023. 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-2023-4753 in the wild and no public exploit code.\n\nAffected product: Openatom Openharmony. 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-2023-4753/ (Markdown: https://insights.sbomify.com/CVE-2023-4753/index.md)","id":"CVE-2023-4753","markdown":"https://insights.sbomify.com/CVE-2023-4753/index.md","name":"CVE-2023-4753","record":{"aliases":["GHSA-pf26-2rq7-37g6"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenHarmony OS","requires_auth":"low_privilege","summary":"Local attackers can crash the OpenHarmony kernel by providing erroneous input to a system call function.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OpenHarmony","cpe":[{"product":"openharmony","vendor":"openatom"}],"cvss":{"score":3.9,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"OpenHarmony v3.2.1 and prior version has a system call function usage error.
