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-2026-63278 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-2026-63278/ (Markdown: https://insights.sbomify.com/CVE-2026-63278/index.md)","id":"CVE-2026-63278","markdown":"https://insights.sbomify.com/CVE-2026-63278/index.md","name":"CVE-2026-63278","record":{"aliases":["DEBIAN-CVE-2026-63278","ECHO-0e64-158a-542b","GHSA-74rr-xj7r-w3qp","MINI-99xm-fh86-f67m","UBUNTU-CVE-2026-63278"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"LibreOffice","requires_auth":"low_privilege","summary":"Attackers can exfiltrate sensitive environment variables and INI file values by tricking users into opening documents with malicious package URLs.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Document Fdn.","cpe":[],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:P/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"URLs could be constructed which expanded environment variable or INI file values, so potentially sensitive information could be exfiltrated to a remote server on opening a document containing such links.
