Original 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. The check added for CVE-2024-12426 did not cover every place a document can supply a URL. XForms instance data and the Calc csv and sql data providers still reached the expansion. In fixed versions these places refuse URLs with internal schemes when the URL comes from the document.
