libreoffice: LibreOffice Calc can link a cell range to an external csv data source, and the link is saved in the document
CVE-2026-63267 is fixed in libreoffice on 1 platform, first by DEBIAN-CVE-2026-63267, released October 5, 2026. It is not reported as exploited. Patch Radar priority: Routine.
LibreOffice Calc can link a cell range to an external csv data source, and the link is saved in the document. Such a link was fetched while the document loaded, so opening a document could read a local file into the sheet, or make a request to a host of the document's choosing. In fixed versions external data links are updated under the same link update control as other links in a spreadsheet.
