Hi, The following vulnerability was published for qt6-base. CVE-2025-5455[0]: | An issue was found in the private API function qDecodeDataUrl() in | QtCore, which is used in QTextDocument and QNetworkReply, and, | potentially, in user code. If the function was called with | malformed data, for example, an URL that contained a "charset" | parameter that lacked a value (such as "data:charset,"), and Qt was | built with assertions enabled, then it would hit an assertion, | resulting in a denial of service (abort). This impacts Qt up to | 5.15.18, 6.0.0->6.5.8, 6.6.0->6.8.3 and 6.9.0. This has been fixed | in 5.15.19, 6.5.9, 6.8.4 and 6.9.1. https://codereview.qt-project.org/c/qt/qtbase/+/642006 If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
