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-2021-26237 and fix it if it is affected.\n\nWhat it is: CVE-2021-26237 is a high-severity memory corruption vulnerability in n/a, published on 18 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-2021-26237 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-26237/ (Markdown: https://insights.sbomify.com/CVE-2021-26237/index.md)","id":"CVE-2021-26237","markdown":"https://insights.sbomify.com/CVE-2021-26237/index.md","name":"CVE-2021-26237","record":{"aliases":["GHSA-g3q2-r548-p52f"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Image viewer application","requires_auth":"none","summary":"A memory corruption vulnerability in FastStone Image Viewer allows attackers to cause a denial of service or potentially execute arbitrary code via a malformed CUR file.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"image_viewer","vendor":"faststone"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","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":"FastStone Image Viewer \u003c= 7.5 is affected by a user mode write access violation at 0x00402d7d, triggered when a user opens or views a malformed CUR file that is mishandled by FSViewer.exe.
