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

1) An error when handling certain actions on network wide plugins can
be exploited by site administrators to disable a network wide plugin.

2) Certain input passed via redirects after posting comments and via
the filtering of URLs 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.

3) Certain input passed via URLs within attributes is not properly
sanitised before being used to make links clickable. 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
if malicious data is viewed.

The vulnerabilities are reported in versions prior to 3.3.2.

SOLUTION:
Update to version 3.3.2.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits:
1) Jon Cave, WordPress core security team and Adam Backstrom.
2) Mauro Gentile.
3) Jon Cave.
