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-2021-43016 and fix it if it is affected.\n\nWhat it is: CVE-2021-43016 is a medium-severity vulnerability in Adobe Incopy, published on 22 Nov 2021. 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-2021-43016 in the wild and no public exploit code.\n\nAffected product: Adobe Incopy. 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-2021-43016/ (Markdown: https://insights.sbomify.com/CVE-2021-43016/index.md)","id":"CVE-2021-43016","markdown":"https://insights.sbomify.com/CVE-2021-43016/index.md","name":"CVE-2021-43016","record":{"aliases":["GHSA-m59q-4q6x-67mj"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Adobe InCopy","requires_auth":"none","summary":"An attacker can cause a denial of service in Adobe InCopy by tricking a user into opening a specially crafted file.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"adobe","cpe":[{"product":"incopy","vendor":"adobe"}],"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-476","name":"NULL Pointer Dereference"}],"description":"Adobe InCopy version 16.4 (and earlier) is affected by a Null pointer dereference vulnerability when parsing a specially crafted file.
