| Description | The Link Widget accepts its `text` field as an unrestricted `sfValidatorString` in `dmFrontPlugin/lib/dmWidget/link/dmWidgetContentLinkForm.php`. Its view in `dmWidgetContentLinkView.php` applies `nl2br()` and passes the result to `dmBaseLinkTag::text()`. `dmCorePlugin/lib/view/html/link/dmBaseLinkTag.php` inserts the value directly between `<a>` tags without HTML encoding. A user with the `widget_edit_fast` or `widget_edit` credential can persist markup such as `<img src=x onerror=alert(document.domain)>`, which executes for every visitor who loads a page containing that widget. |
