The WP Inventory Manager plugin for WordPress is vulnerable to time-based SQL Injection via 'sortorder' Shortcode Attribute in all versions up to, and including, 2.5.5 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This can be exploited by a Contributor via the [wpinventorycategories] shortcode embedded in a draft post rendered through preview, without requiring the post to be published.

The WP Inventory Manager plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'message' parameter in all versions up to, and including, 2.3.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
