How to fix?

There is no fixed version for Debian:unstable qtbase-opensource-src.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qtbase-opensource-src package and not the qtbase-opensource-src package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

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.
