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-2023-21608 in the wild since at least 10 Oct 2023.\n\nAffected product: Adobe Acrobat. 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-2023-21608/ (Markdown: https://insights.sbomify.com/CVE-2023-21608/index.md)","id":"CVE-2023-21608","markdown":"https://insights.sbomify.com/CVE-2023-21608/index.md","name":"CVE-2023-21608","record":{"aliases":["GHSA-w7q6-mhgp-7c2h"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PDF reader","requires_auth":"none","summary":"Attackers can execute arbitrary code by tricking users into opening a malicious PDF file in Adobe Acrobat Reader.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"adobe","cpe":[{"product":"acrobat","vendor":"adobe"},{"product":"acrobat_dc","vendor":"adobe"},{"product":"acrobat_reader","vendor":"adobe"},{"product":"acrobat_reader_dc","vendor":"adobe"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Adobe Acrobat Reader versions 22.003.20282 (and earlier), 22.003.20281 (and earlier) and 20.005.30418 (and earlier) are affected by a Use After Free vulnerability that could result in arbitrary code execution in the context of the current user.
