Description Adam Mariš 2016-09-06 09:38:23 UTC
It was found that z3c.form currently accepts data from GET requests when the form is supposed to be POST. This allows a user to inject a potential XSS attack into a form. With certain widgets in Plone admin forms, the input is expected to be safe and can cause a reflected XSS attack. Additionally, there is potential for an attack that will trick a user into saving a persistent XSS.
