CVSS: 8.4EPSS: 0%CPEs: 3EXPL: 0CVE-2025-5455 – Possible denial of service when passing malformed data in a URL to qDecodeDataUrl
https://notcve.org/view.php?id=CVE-2025-5455
02 Jun 2025 — 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 fixe... • https://codereview.qt-project.org/c/qt/qtbase/+/642006 • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •
