be exploited by malicious users to conduct script insertion attacks.

Input passed to the "homepage address" field isn't sanitised before
being stored in the user profile. This can be exploited to execute
arbitrary HTML and script code in a user's browser session in context
of an affected website when a malicious profile is viewed.

The vulnerability has been reported in version 4.01. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
