WP Recipe Maker < 9.1.1 - Contributor+ Stored Cross-Site Scripting via header_tag

Description

The plugin is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in all versions up to, and including, 9.1.0 due to unrestricted use of the 'header_tag' attribute. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
