Exploitation requires only that the application parse attacker-influenced XML; no authentication, privileges, or user interaction beyond ingesting the input are needed. There is no loss of confidentiality or integrity — no data disclosure, data modification, or code execution — and the impact is contained to the affected process.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-407"],"vendors":[],"products":[],"references":[{"url":"https://codereview.qt-project.org/c/qt/qtbase/+/738885","tags":[]},{"url":"https://codereview.qt-project.org/c/qt/qtbase/+/738901","tags":[]},{"url":"https://wiki.qt.io/List_of_known_vulnerabilities_in_Qt_products#CVE-2026-16762:","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
