CVE-2013-4445 is a medium-severity flaw (CVSS 4.9) affecting context. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The json rendering functionality in the Context module 6.x-2.x before 6.x-3.2 and 7.x-3.x before 7.x-3.0 for Drupal uses Drupal's token scheme to restrict access to blocks, which makes it easier for remote authenticated users to guess the access token for a block by leveraging the token from a block to which the user has access.
