CVE-2025-14576 2 Qt, The Qt Company 2 Qtdeclarative, Qt 2026-05-05 7.8 High
Insufficient validation of node IDs in Qt SVG module allows arbitrary QML/JavaScript code injection when loading malicious SVG files through the VectorImage component in Qt Quick. While QML execution is typically more restricted than native code execution, this could still lead to denial of service, information disclosure, or other impacts depending on the application's privilege level and data access.
CVE-2009-2700 1 Qt 1 Qt 2026-04-23 N/A
src/network/ssl/qsslcertificate.cpp in Nokia Trolltech Qt 4.x does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
CVE-2006-4811 2 Qt, Redhat 3 Qt, Enterprise Linux, Kdelibs 2026-04-23 N/A
Integer overflow in Qt 3.3 before 3.3.7, 4.1 before 4.1.5, and 4.2 before 4.2.1, as used in the KDE khtml library, kdelibs 3.1.3, and possibly other packages, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted pixmap image.
CVE-2007-0242 2 Qt, Redhat 2 Qt, Enterprise Linux 2026-04-23 N/A
The UTF-8 decoder in codecs/qutfcodec.cpp in Qt 3.3.8 and 4.2.3 does not reject long UTF-8 sequences as required by the standard, which allows remote attackers to conduct cross-site scripting (XSS) and directory traversal attacks via long sequences that decode to dangerous metacharacters.
CVE-2025-6338 2 Microsoft, Qt 2 Windows, Qt 2026-04-15 N/A
There is an incomplete cleanup vulnerability in Qt Network's Schannel support on Windows which can lead to a Denial of Service over a long period.This issue affects Qt from 5.15.0 through 6.8.3, from 6.9.0 before 6.9.2.
CVE-2025-23050 1 Qt 1 Qt 2026-04-15 3.1 Low
QLowEnergyController in Qt before 6.8.2 mishandles malformed Bluetooth ATT commands, leading to an out-of-bounds read (or division by zero). This is fixed in 5.15.19, 6.5.9, and 6.8.2.
CVE-2025-10729 1 Qt 1 Qt 2026-04-15 8.6 High
The module will parse a <pattern> node which is not a child of a structural node. The node will be deleted after creation but might be accessed later leading to a use after free.
CVE-2025-10728 1 Qt 1 Qt 2026-04-15 4.0 Medium
When the module renders a Svg file that contains a <pattern> element, it might end up rendering it recursively leading to stack overflow DoS
CVE-2025-3512 1 Qt 1 Qt 2026-04-15 3.3 Low
There is a Heap-based Buffer Overflow vulnerability in QTextMarkdownImporter. This requires an incorrectly formatted markdown file to be passed to QTextMarkdownImporter to trigger the overflow.This issue affects Qt from 6.8.0 to 6.8.4. Versions up to 6.6.0 are known to be unaffected, and the fix is in 6.8.4 and later.
CVE-2024-39936 2 Qt, Redhat 7 Qt, Enterprise Linux, Rhel Aus and 4 more 2025-11-29 8.6 High
An issue was discovered in HTTP2 in Qt before 5.15.18, 6.x before 6.2.13, 6.3.x through 6.5.x before 6.5.7, and 6.6.x through 6.7.x before 6.7.3. Code to make security-relevant decisions about an established connection may execute too early, because the encrypted() signal has not yet been emitted and processed..
CVE-2024-36048 2 Fedoraproject, Qt 3 Fedora, Qt, Qt Network Authorization 2025-11-05 9.8 Critical
QAbstractOAuth in Qt Network Authorization in Qt before 5.15.17, 6.x before 6.2.13, 6.3.x through 6.5.x before 6.5.6, and 6.6.x through 6.7.x before 6.7.1 uses only the time to seed the PRNG, which may result in guessable values.
CVE-2024-25580 2 Qt, Redhat 2 Qt, Enterprise Linux 2025-11-04 6.2 Medium
An issue was discovered in gui/util/qktxhandler.cpp in Qt before 5.15.17, 6.x before 6.2.12, 6.3.x through 6.5.x before 6.5.5, and 6.6.x before 6.6.2. A buffer overflow and application crash can occur via a crafted KTX image file.
CVE-2025-5683 1 Qt 1 Qt 2025-10-15 5.5 Medium
When loading a specifically crafted ICNS format image file in QImage then it will trigger a crash. This issue affects Qt from versions 6.3.0 through 6.5.9, from 6.6.0 through 6.8.4, 6.9.0. This is fixed in 6.5.10, 6.8.5 and 6.9.1.
CVE-2024-30161 1 Qt 1 Qt 2025-06-30 6.5 Medium
In Qt 6.5.4, 6.5.5, and 6.6.2, QNetworkReply header data might be accessed via a dangling pointer in Qt for WebAssembly (wasm). (Earlier and later versions are unaffected.)
CVE-2017-10904 1 Qt 1 Qt 2025-04-20 N/A

CVE-2016-10040 1 Qt 1 Qxmlsimplereader 2025-04-20 N/A
Stack-based buffer overflow in QXmlSimpleReader in Qt 4.8.5 allows remote attackers to cause a denial of service (application crash) via a xml file with multiple nested open tags.
CVE-2015-8079 1 Qt 1 Qtwebkit 2025-04-20 5.3 Medium
