A vulnerability has been reported in the Project issue tracking module for Drupal, which can be exploited by malicious users to disclose sensitive information.

The problem is that it is possible to view issues, even when they are marked private using a node access module.

Successful exploitation requires knowledge of the node identifier, valid user credentials, and that the user has the "Access project issues" permission.

The vulnerability is reported in the 4.7.x-1.x branch prior to version 4.7.x-1.3 and the 4.7.x-2.x branch prior to version 4.7.x-2.3.

Solution
Update to version 4.7.x-1.3 or 4.7.x-2.3.
