DESCRIPTION:
A vulnerability has been reported in the Authoring HTML module for
Drupal, which can be exploited by malicious users to bypass certain
security restrictions.

The vulnerability is caused due to the module not properly validating
the source of embedded scripts against the whitelist and can be
exploited to embed scripts from malicious sites.

This can further be exploited to conduct script insertion attacks.

Successful exploitation requires permission to use the Authoring HTML
input format.

The vulnerability is reported in versions 6.x-1.x prior to 6.x-1.1.

SOLUTION:
Update to version 6.x-1.1.
