Technical details
A vulnerability exists in wp-admin/includes/class-wp-press-this.php within the 'Press This' component of WordPress. The application fails to perform adequate capability checks before displaying the user interface for assigning taxonomy terms (categories and tags). As a result, remote attackers can access this interface and read existing terms without having the necessary permissions to manage them. This is classified as an information exposure vulnerability (CWE-200). The issue was addressed in WordPress version 4.7.2 by implementing proper permission checks to ensure the UI is only visible to authorized users.
