CVE-2026-63267

The Document Foundation LibreOffice CWE-918

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.
