- 1.9LowOct 27, 2026Qt Memory corruptionCVE-2026-107590An 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.
- 4.3MediumOct 27, 2026Qt Memory corruptionCVE-2026-107472An 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.
- 5.3MediumOct 27, 2026qt Memory corruptionCVE-2026-105946Out-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.
- 2.0LowOct 26, 2026Qt Memory corruptionCVE-2026-107157Specially 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.
- 2.1LowOct 26, 2026qt Memory corruptionCVE-2026-96432A 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.
- 2.1LowOct 23, 2026qt Memory corruptionCVE-2026-95620A 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.
- 8.7HighOct 23, 2026qt Denial of serviceCVE-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 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
- 6.8MediumJul 16, 2026Qt AxivionCVE-2026-12379An Open Redirect vulnerability (CWE-601) exists in the OAuth/OIDC authentication implementation of the Axivion Dashboard. The login flow did not properly restrict the post-authentication redirect to the application's own origin, so a user who follows a crafted login link can be sent to an untrusted external site after authenticating against the genuine Dashboard. Because the link points at the legitimate Dashboard, this can be abused for phishing, for example credential or second-factor theft vi
