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-2026-48421 and fix it if it is affected.\n\nWhat it is: CVE-2026-48421 is a high-severity memory corruption vulnerability in Adobe Substance 3D Sampler, published on 25 Aug 2026. 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-2026-48421 in the wild and no public exploit code.\n\nAffected product: Adobe Substance 3D Sampler. 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-2026-48421/ (Markdown: https://insights.sbomify.com/CVE-2026-48421/index.md)","id":"CVE-2026-48421","markdown":"https://insights.sbomify.com/CVE-2026-48421/index.md","name":"CVE-2026-48421","record":{"aliases":["GHSA-722c-v8j2-6qp9"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"3D design software","requires_auth":"none","summary":"An out-of-bounds write vulnerability in Adobe Substance 3D Sampler allows arbitrary code execution when a user opens a malicious file.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"adobe","cpe":[{"product":"substance_3d_sampler","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-787","name":"Out-of-bounds Write"}],"description":"Substance3D - Sampler is affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user.
