## Overview

The WP BookWidgets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'bw_link' shortcode in all versions up to, and including, 0.9 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
