Descriptions

The Contact Form Plugin WordPress plugin before 4.3.25 does not properly sanitize and escape the srcdoc attribute in iframes in it's custom HTML field type, allowing a logged in user with roles as low as contributor to inject arbitrary javascript into a form which will trigger for any visitor to the form or admins previewing or editing the form.

The FluentForms plugin for WrodPress is vulnerable to stored Cross-Site Scripting via custom form fields in versions up to, and including, 4.3.24. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
