There is a really good article from ManageWP.com about WordPress security. I recommend reading it if you are concerned that other content management systems may be more secure than WordPress. The take-away is this: The main vulnerability in WordPress is out of date software and common username/password combinations.
The beauty of WordPress is the ease of updating software and the ease of changing usernames and passwords. With one click the main core of WordPress can be updated as soon as a security patch has been released and with another click plugins and themes can be updated in the same way. Other content management systems that I have worked on have fairly complicated upgrading systems that often require manual replacement of files via an FTP client. With this taken into consideration, the security vulnerability lies in the hands of the end user. It is extremely important that software is kept up to date and that passwords are unique and hard to guess.
