Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
We found a possible XSS vector in the `FlamingoThemesCode.WebHomeSheet` wiki page related to the "newThemeName" form field.
### Patches
The issue is patched in versions 12.10.11, 14.0-rc-1, 13.4.7, 13.10.3.
### Workarounds
The easiest workaround is to edit the wiki page `FlamingoThemesCode.WebHomeSheet` (with wiki editor) and change the line
```
<input type="hidden" name="newThemeName" id="newThemeName" value="$request.newThemeName" />
```
into
```
<input type="hidden" name="newThemeName" id="newThemeName" value="$escapetool.xml($request.newThemeName)" />
```
