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-2021-39823 in the wild and no public exploit code.\n\nAffected product: Adobe SVG Native Viewer. 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-2021-39823/ (Markdown: https://insights.sbomify.com/CVE-2021-39823/index.md)","id":"CVE-2021-39823","markdown":"https://insights.sbomify.com/CVE-2021-39823/index.md","name":"CVE-2021-39823","record":{"aliases":["GHSA-62gh-7323-4v89"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"SVG rendering library","requires_auth":"none","summary":"Heap buffer overflow in Adobe svg-native-viewer allows arbitrary code execution via malicious SVG files, requiring user interaction.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"adobe","cpe":[{"product":"svg-native-viewer","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-122","name":"Heap-based Buffer Overflow"}],"description":"Adobe svg-native-viewer 8182d14dfad5d1e10f53ed830328d7d9a3cfa96d and earlier versions are affected by a heap buffer overflow vulnerability due to insecure handling of a malicious .svg file, potentially resulting in arbitrary code execution in the context of the current user.
