| CVE-2026-107590 | 1 Qt | 3 Qt, Qt5compat, Qtbase | 2026-10-27 | N/A |
| An out-of-bounds write vulnerability in the Qt QTextCodec iconv-based encoding of the Qt 5 Compatibility APIs module (Qt Core in Qt 5 and earlier) impacts Qt. Under certain conditions, encoding text with QTextCodec may write outside an internal buffer. This can cause the application to crash and may affect data integrity. | ||||
| CVE-2026-107157 | 1 Qt | 2 Qt, Qtbase | 2026-10-27 | N/A |
| Specially crafted CBOR input passed to QCborValue::fromCbor() in Qt Core can cause an out-of-bounds read, which may crash the application and could expose information. | ||||
| CVE-2026-107472 | 1 Qt | 3 Qt, Qt5compat, Qtbase | 2026-10-27 | N/A |
| An out-of-bounds read vulnerability in the QTextCodec TSCII encoding of the Qt 5 Compatibility APIs module (Qt Core in Qt 5 and earlier) impacts Qt. Applications that convert text to the TSCII encoding through QTextCodec may read memory outside the input buffer, which can cause the application to crash or misinterpret the data. | ||||
| CVE-2026-105946 | 1 Qt | 2 Qt, Qtbase | 2026-10-27 | N/A |
| Out-of-bounds read in the QAuthenticator NTLM authentication handling in the Qt Network module in Qt Group Qt allows remote attackers to obtain sensitive information (heap memory contents) or cause a denial of service (application crash) via a crafted NTLM challenge sent by a malicious server or proxy, when an application using QNetworkAccessManager or QTcpSocket authenticates with NTLM. | ||||
| CVE-2026-96432 | 1 Qt | 2 Qt, Qtbase | 2026-10-26 | N/A |
| A malicious or compromised HTTP/2 server withholding SETTINGS ACK can send RST_STREAM on a completed stream, planting a null pointer, and then send a PUSH_PROMISE for that stream, causing a null pointer dereference in the QNetworkAccessManager class of the Qt Network module that crashes the application. | ||||
| CVE-2026-95620 | 1 Qt | 1 Qt | 2026-10-23 | N/A |
| A use-after-free vulnerability in the Qt QNetworkAccessManager HTTP/2 client support of the Qt Network module allows a malicious or compromised HTTP/2 server to cause the client application to crash, affecting availability. | ||||
| CVE-2026-16762 | 1 Qt | 2 Qt, Qtbase | 2026-10-23 | N/A |
| An attacker able to supply a crafted XML document to an application using QXmlStreamReader can cause disproportionate CPU consumption during parsing, making the application unresponsive (denial of service). 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. | ||||
| CVE-2026-105923 | 1 Qt | 2 Qt, Qtbase | 2026-10-21 | 5.5 Medium |
| A malicious SVG can trigger an integer overflow which in turn triggers a null-pointer dereference in VectorImage QML Type. | ||||
| CVE-2026-101201 | 1 Qt | 3 Qt, Qt5compat, Qtbase | 2026-10-20 | 5.5 Medium |
| A malformed header in the binary file fed to QBinaryJson::fromBinaryData() can cause undefined behaviour because of out-of-bounds read. | ||||
| CVE-2026-8168 | 1 Qt | 2 Qt, Qtsvg | 2026-10-19 | 6.5 Medium |
| Uncontrolled recursion in the SVG parser and renderer of the Qt SVG module (QtSvg) in Qt Group Qt allows attackers to cause a denial of service (application crash via stack exhaustion) via a crafted SVG file with deeply nested elements. | ||||
| CVE-2020-24742 | 1 Qt | 1 Qt | 2026-10-08 | 7.8 High |
| An issue has been fixed in Qt versions 5.14.0 where QPluginLoader attempts to load plugins relative to the working directory, allowing attackers to execute arbitrary code via crafted files. | ||||
| CVE-2020-0570 | 2 Qt, Redhat | 2 Qt, Enterprise Linux | 2026-10-08 | 7.3 High |
| Uncontrolled search path in the QT Library before 5.14.0, 5.12.7 and 5.9.10 may allow an authenticated user to potentially enable elevation of privilege via local access. | ||||
| CVE-2026-79680 | 1 Qt | 1 Qt | 2026-09-24 | 6.8 Medium |
| Authentication bypass vulnerability in the password authentication mechanism of the Qt VNC Server module. An attacker using a specially modified VNC client that violates the RFB protocol can bypass Qt VNC Server's password authentication and gain unauthorized remote access to the shared application, compromising the confidentiality and integrity of the session. | ||||
| CVE-2026-79616 | 1 Qt | 1 Qt | 2026-09-24 | 4.4 Medium |
| Out-of-bounds read while parsing untrusted SVG path strings in Qt Quick's Context2D.path / PathSvg.path. | ||||
| CVE-2026-78253 | 1 Qt | 1 Qt | 2026-09-23 | 4.7 Medium |
| Uncontrolled recursion in QXmlStreamReader::readElementText() in Qt Group Qt allows attackers to cause a denial of service (application crash via stack exhaustion) via a crafted XML document. | ||||
| CVE-2026-19248 | 1 Qt | 1 Qt | 2026-09-16 | 6.5 Medium |
| QDomDocument XML parsing is vulnerable to a remotely-triggerable denial-of-service crash when processing untrusted input. | ||||
| CVE-2026-76151 | 1 Qt | 1 Qt | 2026-09-16 | N/A |
| Out-of-bounds read (buffer over-read) in the HTTP Cache-Control response header parsing in the QtNetwork module in Qt Group Qt 6.0.0 through 6.8.8, and 6.9.0 through 6.11.1, allows remote attackers to cause a denial of service (application crash) via an excessively large Cache-Control header value returned by an untrusted or compromised HTTP server to an application using QNetworkAccessManager. Only the client side of the connection is affected and 32-bit builds are not affected; the out-of-bounds access is read-only, with no information disclosure and no code execution. | ||||
| CVE-2026-13326 | 1 Qt | 1 Qt | 2026-09-11 | N/A |
| An out-of-bounds read in Qt NFC's language code length parsing allows a physically proximate attacker to cause a denial of service or limited memory disclosure via a crafted NFC tag. | ||||
| CVE-2026-11573 | 1 Qt | 1 Qt | 2026-09-11 | 7.5 High |
| Uncontrolled recursion (CWE-674) in the QDomDocument/QDomNode serialization path of the Qt XML module (QtXml, qtbase). QDomElementPrivate::save() and QDomNodePrivate::save() recurse mutually, consuming one stack frame per level of element nesting with no depth limit, no configurable bound and no error return. A document with deeply nested elements parses successfully but exhausts the call stack and terminates the process when serialized. Reachable via QDomDocument::toByteArray() (Qt 4.0 and later), QDomDocument::toString(), QDomDocument::toCString(), QDomNode::save(), and operator<<(QTextStream&, const QDomNode&). Denial of service only — no code execution and no memory disclosure. | ||||
| CVE-2026-15037 | 1 Qt | 1 Qt | 2026-08-03 | 5.3 Medium |
| Improper output neutralization (XML injection) in QDom comment, CDATA, and processing-instruction serialization in Qt XML from 4.0.0 through 6.11 allows untrusted text serialized by an application into those nodes to inject arbitrary XML markup, because the node terminators are not escaped under the default InvalidDataPolicy (AcceptInvalidChars). Fixed in Qt 6.12. | ||||
