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)" />References
