7.2 High

The Beautiful Cookie Consent Banner for WordPress is vulnerable to Stored Cross-Site Scripting via the 'nsc_bar_content_href' parameter in versions up to, and including, 2.10.1 due to insufficient input sanitization and output escaping.

A partial patch was made available in 2.10.1 and the issue was fully patched in 2.10.2.
