CVE-2026-15037 Details
Description
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.
A vulnerability exists in the Qt XML module, specifically in QDom comment, CDATA, and processing-instruction serialization, in versions 4.0.0 prior to 6.11. This issue stems from improper output neutralization, allowing XML injection via untrusted text. The vulnerability arises because node terminators are not escaped under the default InvalidDataPolicy, which accepts invalid characters. As a result, arbitrary XML markup can be injected into the serialized nodes.
Users can upgrade to Qt version 6.12 or later to address this vulnerability.
