CVE-2026-63278
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 recognise every way of naming the package content provider, so a URL that named it differently still reached the expansion. In fixed versions the package content provider is matched when the URL is checked.
