It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-22484 and fix it if it is affected.\n\nWhat it is: CVE-2023-22484 is a low-severity denial of service vulnerability in github cmark-gfm, published on 23 Jan 2023. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-22484 exists.\n\nAffected product: github cmark-gfm. 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-2023-22484/ (Markdown: https://insights.sbomify.com/CVE-2023-22484/index.md)","id":"CVE-2023-22484","markdown":"https://insights.sbomify.com/CVE-2023-22484/index.md","name":"CVE-2023-22484","record":{"aliases":["DEBIAN-CVE-2023-22484","GHSA-24f7-9frr-5h2r","UBUNTU-CVE-2023-22484"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Markdown parsing library","requires_auth":"low_privilege","summary":"An attacker can cause denial of service in cmark-gfm by submitting input that triggers inefficient quadratic complexity during parsing.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"cmark-gfm","vendor":"github"}],"cvss":{"score":3.5,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-407","name":"Inefficient Algorithmic Complexity"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"cmark-gfm is GitHub's fork of cmark, a CommonMark parsing and rendering library and program in C.
