DESCRIPTION:
Two vulnerabilities have been reported in the A-Form plugins for
Movable Type, which can be exploited by malicious people to conduct
cross-site scripting attacks and bypass certain security
restrictions.

1) Certain unspecified input 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.

Note: This vulnerability only affects "A-Form PC" and "A-Form
PC/Mobile".

2) An error in the application can be exploited to bypass certain
security restrictions and change information managed by the A-Form
plugin.

The vulnerabilities are reported in the following versions:
* A-Form and A-Form Bamboo prior to version 1.3.6
* A-Form and A-Form Bamboo prior to version 2.0.3
* A-Form PC and A-Form PC/Mobile prior to version 3.1

SOLUTION:
Update to a fixed version.
