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-2026-126497 and fix it if it is affected.\n\nWhat it is: CVE-2026-126497 is a high-severity memory corruption vulnerability in LibreCAD, published on 11 Nov 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-2026-126497 in the wild and no public exploit code.\nExposure: An affected version is exposed as installed. No special setting or call is needed.\n\nAffected product: LibreCAD. 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-2026-126497/ (Markdown: https://insights.sbomify.com/CVE-2026-126497/index.md)","id":"CVE-2026-126497","markdown":"https://insights.sbomify.com/CVE-2026-126497/index.md","name":"CVE-2026-126497","record":{"aliases":["DEBIAN-CVE-2026-126497","GHSA-8vq5-h62f-ccwp","UBUNTU-CVE-2026-126497"],"analysis":{"component_type":"desktop_application","exploitable_when_present":false,"fix_type":"no_fix_stated","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"CAD software","requires_auth":"none","requires_specific_call":false,"summary":"A crafted DWG file opened in LibreCAD can trigger a heap overflow, crashing it or possibly executing code.","user_interaction":"required","vuln_class":"memory_corruption","vulnerable_functions":["dwgReader18::parseDataPage"]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"LibreCAD through 2.2.1.6 contains a heap-based out-of-bounds write vulnerability in the bundled libdxfrw dwgReader18::parseDataPage() function due to unchecked buffer size and page offsets.
