DESCRIPTION:
Some vulnerabilities have been reported in Plone, which can be
exploited by malicious users to bypass certain security restrictions
and by malicious people to conduct cross-site scripting and script
insertion attacks

1) Certain input passed to the application is not properly sanitised
before being returned to the user. This can be exploited to execute
arbitrary HTML and script code in a user's browser session in context
of an affected site.

2) Certain input passed via a markup to Portal.PortalTransforms is
not properly sanitised before being used. This can be exploited to
insert arbitrary HTML and script code, which will be executed in a
user's browser session in context of an affected site when the
malicious data is being viewed.

3) An error in plone.app.users does not properly check for
authorisation and can be exploited to edit properties of other
users.

NOTE: This vulnerability is reportedly being exploited in the wild.

SOLUTION:
Apply hotfix 20110531.
