As a member of the Plone security response team I hereby notify you that we have been made aware of three distinct security holes in Plone and are requesting CVE identifiers. 1. Reflected XSS attack A crafted URL can display arbitrary HTML output 2. Persistent XSS attack Certain valid HTML will allow Javascript filtering to be bypassed. 3. Unauthorised data changes One change form for data allows preferences to be changed. No deletion of content of loss of confidentiality is possible. Thanks very much, Matthew
