CVE-2026-16762An attacker able to supply a crafted XML document to an application using QXmlStreamReader can cause disproportionate CPU consumption during parsing, making the application... Executive summary The advisory is about CVE-2026-16762, a denial-of-service flaw in the Qt Core QXmlStreamReader XML parser that can make an application unresponsive when it parses a crafted XML document. The advisory describes the impact as limited to availability, with no data disclosure, data modification, or code execution, and it lists fixed versions of Qt for the affected branches. The text provided does not state a severity score, and the advisory's recommended action is to update to the fixed Qt versions. Technical summary The flaw is a denial-of-service issue caused by disproportionate CPU consumption while the QXmlStreamReader parser handles attacker-supplied XML. Exploitation needs no authentication, privileges, or user interaction beyond the application ingesting the input. Affected versions are stated as from Qt 4.3.0 to Qt 6.8.8 and from Qt 6.9.0 to Qt 6.11.1, with status before Qt 4.3.0 described as unknown. Fixed versions are Qt 6.8.9, Qt 6.11.2, and Qt 6.12.0. The advisory does not state a workaround, a CVSS score, or any detection guidance, and it does not say whether the issue is exploited in the wild. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
