CWE-415 14/10/2026
Memory corruption (double free / use-after-free) vulnerability in core string handling impacts Qt for MCUs
A defect in the Qt for MCUs core string handling causes heap memory corruption. When an application passes text into Qt Quick Ultralite using the public Qul::String interface type, and that text is held in a std::string, the conversion to the internal string type copies the pointer without taking ownership of it. Two objects then release the same memory, producing a double free, an invalid free, or a use-after-free.

CWE-230 05/10/2026
An empty <img> attribute value in styled text triggers a parser error that halts the device.
In Qt for MCUs, a Text element that displays styled text halts the device if an <img> tag in the text contains an attribute with an empty value. The text parser passes the empty value to an internal check that only accepts non-empty values. The check fails and reports an error, and the default error handler halts the device.

CWE-601 16/07/2026
URL Redirection to Untrusted Site ('Open Redirect') vulnerability in the Dashboard OAuth/OIDC implementation of Axivion
An 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 via a convincing look-alike page. Exploitation requires the victim to follow the attacker-supplied link and complete the authentication flow.

CWE-862 09/07/2026
Privilege escalation via forged API token creation in Axivion Dashboard OIDC/OAuth2/SSO subsystem
The implementation of an internal and undocumented Dashboard API endpoint (POST /api/users/~/{user}/tokens) forgot to ensure an HTTP request for creating an API Token for another user had sufficient permission to do so.
Precondition for successful exploitation was a preexisting internal user (with more privileges than the attacker), the attacker knowing its login name and the attacker being able to authenticate to the Dashboard via OAuth/OIDC. The attacker would then have had to forge a token creation API request on behalf of the other user and could have authenticated and finalized the token creation with their own OAuth/OIDC credentials. In the worst case, this would mean an attacker could have become Dashboard Administrator and been able to perform all administrative actions if the preexisting internal user had administrative privileges. In combination with a separate weakness, this could have further led to code execution on the host system running the Dashboard with the privileges of the OS-User running the Dashboard server.

CWE-427 19/05/2026
Uncontrolled Search Path Element in Qt Network OpenSSL TLS backend allows rogue CA certificate loading
An Uncontrolled Search Path Element vulnerability in the OpenSSL TLS backend of Qt Network (qtbase) in Qt Qt Framework (Unix) allows a local attacker to load a rogue CA certificate as a trusted system authority via a crafted certificate file placed in the application's working directory.

CWE-122 06/05/2026
Type confusion and heap-buffer-overflow in Qt SVG marker handling causing application crash
A type confusion vulnerability in Qt SVG allows an attacker to cause an application crash via a crafted SVG image.
When processing SVG marker references, the renderer retrieves a node by its id attribute and casts it to QSvgMarker* without verifying the node type. A non-marker element (such as a <line> element) that references itself as a marker triggers an out-of-bounds heap read due to the object size difference between QSvgLine and QSvgMarker,
followed by an endless recursion that bypasses the marker recursion
guard through incorrect virtual dispatch. The result is an application
crash (denial of service).
This issue affects Qt SVG:
from 6.7.0 before 6.8.8, from 6.9.0 before 6.11.1.

CWE-94 30/04/2026
Possible QML code injection in VectorImage component
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.

CWE-770 03/12/2025
Improper validation of <img> tag size in Text component parser
Allocation of Resources Without Limits or Throttling, Improper Validation of Specified Quantity in Input vulnerability in The Qt Company Qt on Windows, MacOS, Linux, iOS, Android, x86, ARM, 64 bit, 32 bit allows Excessive Allocation.
This issue affects users of the Text component in Qt Quick. Missing validation of the width and height in the <img> tag could cause an application to become unresponsive.
This issue affects Qt: from 5.0.0 through 6.5.10, from 6.6.0 through 6.8.5, from 6.9.0 through 6.10.0.

Out-of-bounds Read em Qt
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.

Use-after-free vulnerability in Qt SVG qsvghandler.cpp allows denial of service via crafted SVG
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.
