WPComplete vulnerabilities

Unauthenticated Cross Site Scripting (XSS) in WPComplete versions up to 2.9.5.6. Allows injecting malicious script into the page.

The WPComplete plugin for WordPress (versions up to and including 2.9.9.0) is vulnerable to Stored Cross-Site Scripting via the 'empty' Shortcode Attribute due to insufficient input sanitization and output escaping. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts into pages that execute whenever a user accesses an injected page. This requires the premium version of the software. Please note this only affects the pro version.

The WPComplete plugin has a missing authorization vulnerability, allowing access to functionality not properly constrained by ACLs. Affects versions up to and including 2.9.5.3.
