What is CVE-2025-30348?

The Qt Framework, prior to version 6.8.0, is susceptible to an XML string encoding issue stemming from the 'encodeText' method in QDom. The flaw involves a complex algorithm that mismanages XML string copying and incorporates inline replacements within the string, leading to potential data breaches. This could allow attackers to manipulate XML data in a way that disrupts application functionality or compromises user information.
