Description
The Media Library Assistant plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'author' field-level substitution parameters in all versions up to, and including, 3.42 due to the plugin allowing any WP_User property or user meta value to be read without restricting which fields may be accessed. This makes it possible for authenticated attackers, with contributor-level access and above, to place shortcodes such as mla_gallery with parameters like [+author:user_email+] or [+author:user_pass+] in a post and extract sensitive data, including email addresses and password hashes, of attachment authors.
