CVE-2025-64403

Estado: AnalizadaAlta (8.1)—

Apache OpenOffice Calc spreadsheet can contain links to other files, in the form of "external data sources". A missing Authorization vulnerability in Apache OpenOffice allowed an attacker to craft a document that would cause such links to be loaded without prompt.

This issue affects Apache OpenOffice: through 4.1.15.

Users are recommended to upgrade to version 4.1.16, which fixes the issue.
