CVE Reference(s):

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.
