Security risk: *Moderately critical* 10∕25
AC:Basic/A:None/CI:None/II:None/E:Theoretical/TD:All [2]
Vulnerability: Open Redirect

Description: 
Drupal 7 has an Open Redirect vulnerability. For example, a user could be
tricked into visiting a specially crafted link which would redirect them to
an arbitrary external URL.

The vulnerability is caused by insufficient validation of the destination
query parameter in the drupal_goto() function.

Other versions of Drupal core are not vulnerable.

Solution: 
Install the latest version:

  * If you use Drupal 7.x upgrade to Drupal 7.70 [3]
