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-2021-40764 and fix it if it is affected.\n\nWhat it is: CVE-2021-40764 is a high-severity memory corruption vulnerability in Adobe Character Animator (Preview 4), published on 16 Mar 2022. 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-2021-40764 in the wild and no public exploit code.\n\nAffected product: Adobe Character Animator (Preview 4). 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-2021-40764/ (Markdown: https://insights.sbomify.com/CVE-2021-40764/index.md)","id":"CVE-2021-40764","markdown":"https://insights.sbomify.com/CVE-2021-40764/index.md","name":"CVE-2021-40764","record":{"aliases":["GHSA-qg8w-fqf6-rhhv"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Adobe Character Animator","requires_auth":"none","summary":"An attacker can execute arbitrary code by tricking a user into opening a malicious M4A file in Adobe Character Animator.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"adobe","cpe":[{"product":"character_animator","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-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"},{"id":"CWE-788","name":"Access of Memory Location After End of Buffer"}],"description":"Adobe Character Animator version 4.4 (and earlier) is affected by a memory corruption vulnerability when parsing a M4A file, potentially resulting in arbitrary code execution in the context of the current user.
