Improper Link Resolution Before File Access ('Link Following') vulnerability in QFileSystemEngine in the Qt corelib module on Windows which potentially allows Symlink Attacks and the use of Malicious Files. Issue originates from CVE-2024-38081. The vulnerability arises from the use of the GetTempPath API, which can be exploited by attackers to manipulate temporary file paths, potentially leading to unauthorized access and privilege escalation. The affected public API in the Qt Framework is QDir::tempPath() and anything that uses it, such as QStandardPaths with TempLocation, QTemporaryDir, and QTemporaryFile. This issue affects all version of Qt up to and including 5.15.18, from 6.0.0 through 6.5.8, from 6.6.0 through 6.8.1. It is fixed in Qt 5.15.19, Qt 6.5.9, Qt 6.8.2, 6.9.0
