DESCRIPTION:
A vulnerability has been reported in the Hashcash module for Drupal,
which can be exploited by malicious people to conduct script
insertion attacks.

Input passed via an invalid token 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.

Successful exploitation requires that "Log failed hashcash" is
enabled (disabled by default).

The vulnerability is reported in versions 6.x-2.x prior to 6.x-2.6
and 7.x-2.x prior to 7.x-2.2.

SOLUTION:
Update to a patched version.
