## Affected

- Unknown Featured Image with URL: fixed in 1.0.6

## Description

The Featured Image with URL WordPress plugin before 1.0.6 does not sanitise and escape a stored image attribute value before outputting it, which could allow users with a role as low as Contributor to perform Stored Cross-Site Scripting attacks that execute in the browser of any user viewing the affected post, including higher-privileged users such as Editors and Administrators.
