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-2026-63274 in the wild and no public exploit code.\n\nAffected product: The Document Foundation LibreOffice. 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-2026-63274/ (Markdown: https://insights.sbomify.com/CVE-2026-63274/index.md)","id":"CVE-2026-63274","markdown":"https://insights.sbomify.com/CVE-2026-63274/index.md","name":"CVE-2026-63274","record":{"aliases":["DEBIAN-CVE-2026-63274","ECHO-8494-a0dc-6b0c","GHSA-q9rh-47xp-mj2m","MINI-v329-wf69-59m2","UBUNTU-CVE-2026-63274"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"LibreOffice Draw","requires_auth":"none","summary":"Heap buffer overflow in LibreOffice Draw PDF import allows attackers to execute arbitrary code or cause denial of service via malicious documents.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Document Fdn.","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"LibreOffice Draw can import PDF documents.
