Cross-site Scripting in the Flamingo theme manager

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)" />
