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-2021-21056 and fix it if it is affected.\n\nWhat it is: CVE-2021-21056 is a high-severity memory corruption vulnerability in Adobe Framemaker, published on 12 Mar 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-2021-21056 in the wild and no public exploit code.\n\nAffected product: Adobe Framemaker. 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-2021-21056/ (Markdown: https://insights.sbomify.com/CVE-2021-21056/index.md)","id":"CVE-2021-21056","markdown":"https://insights.sbomify.com/CVE-2021-21056/index.md","name":"CVE-2021-21056","record":{"aliases":["GHSA-gj48-77xm-g7jj"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Adobe FrameMaker","requires_auth":"none","summary":"An attacker can achieve arbitrary code execution by tricking a user into opening a specially crafted file in Adobe FrameMaker.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"adobe","cpe":[{"product":"framemaker","vendor":"adobe"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Adobe Framemaker version 2020.0.1 (and earlier) is affected by an Out-of-bounds Read vulnerability when parsing a specially crafted file.
