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-2021-40724 and fix it if it is affected.\n\nWhat it is: CVE-2021-40724 is a high-severity path traversal vulnerability in Adobe Acrobat Reader, published on 15 Oct 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-2021-40724 in the wild and no public exploit code.\n\nAffected product: Adobe Acrobat Reader. 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-2021-40724/ (Markdown: https://insights.sbomify.com/CVE-2021-40724/index.md)","id":"CVE-2021-40724","markdown":"https://insights.sbomify.com/CVE-2021-40724/index.md","name":"CVE-2021-40724","record":{"aliases":["GHSA-29r2-9wmj-m244"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Adobe Acrobat Reader","requires_auth":"none","summary":"An attacker can achieve arbitrary code execution by tricking a user into opening a malicious file in Adobe Acrobat Reader for Android.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"adobe","cpe":[{"product":"acrobat_reader","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-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Acrobat Reader for Android versions 21.8.0 (and earlier) are affected by a Path traversal vulnerability.
