Summary
The Alba Board plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.1.3. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to access arbitrary private alba_card post data, including title, description, assignee, due date, tags, and comments, that is intended to be restricted to Administrators and Editors. The handler is registered via the wp_ajax_nopriv_ hook and its nonce is exposed to all site visitors through wp_localize_script on pages containing the [alba_board] shortcode, making this exploitable by unauthenticated users who can access any such page.
