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-2021-28634 and fix it if it is affected.\n\nWhat it is: CVE-2021-28634 is a high-severity command injection vulnerability in Adobe Acrobat Dc, published on 20 Aug 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-2021-28634 in the wild and no public exploit code.\n\nAffected product: Adobe Acrobat Dc. 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-2021-28634/ (Markdown: https://insights.sbomify.com/CVE-2021-28634/index.md)","id":"CVE-2021-28634","markdown":"https://insights.sbomify.com/CVE-2021-28634/index.md","name":"CVE-2021-28634","record":{"aliases":["GHSA-v8vj-969w-qv4m"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Adobe Acrobat Reader","requires_auth":"low_privilege","summary":"An attacker can execute arbitrary code on the host by tricking a user into opening a malicious file in Adobe Acrobat Reader.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"adobe","cpe":[{"product":"acrobat_dc","vendor":"adobe"},{"product":"acrobat_reader_dc","vendor":"adobe"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Acrobat Reader DC versions 2021.005.20054 (and earlier), 2020.004.30005 (and earlier) and 2017.011.30197 (and earlier) are affected by an Improper Neutralization of Special Elements used in an OS Command.
