Description

Fixes # XSS attack

If you use getHTML, some specific attack tags will not be processed because the execution precondition of escapeHtml is that the variable exists “<>” at the same time.

The following tags will not be escaped and the attack script will be executed:
<img src=x onxss="" onerror="alert(document.cookie);"
