CVE-2026-15037[0]:
| 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.
