Does this matter?

Lower severity and a low EPSS score (0.45%). Track it; it rarely justifies an emergency change on its own.

Description

Starting in version 1.0.12 and prior to version 1.1.12, when calling the extended toHTMLEx method, it is possible to execute arbitrary JavaScript code. Version 1.1.12 fixes the issue. As a workaround, don't use direct publication via toHTMLEx.
