Apache OpenOffice: Remote documents loaded without prompt via IFrame

Vulnerability Description

Apache OpenOffice documents can contain links. A missing Authorization vulnerability in Apache OpenOffice allowed an attacker to craft a document that would cause external links to be loaded without prompt. In the affected versions of Apache OpenOffice, documents that used "floating frames" linked to external files would load the contents of those frames without prompting the user for permission to do so. This issue affects Apache OpenOffice: through 4.1.15. Users are recommended to upgrade to version 4.1.16, which fixes the issue. The LibreOffice suite reported this issue as CVE-2023-2255
