Name of the Vulnerable Software and Affected Versions: WP Booking Calendar plugin for WordPress versions up to, and including, 10.11.1

Description: The issue is related to Stored Cross-Site Scripting via the plugin's wpbc shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows 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.

Recommendations: For WP Booking Calendar plugin for WordPress versions up to, and including, 10.11.1, update to a version higher than 10.11.1 to resolve the issue. As a temporary workaround, consider restricting access to the wpbc shortcode for users with contributor-level access and above until a patch is available.
