Descriptions
The RSS Aggregator by Feedzy WordPress plugin before 4.1.1 does not validate and escape some of its block options before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins.
The RSS Aggregator by Feedzy plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcodes in versions up to, and including, 4.1.0 due to insufficient input sanitization and output escaping on user supplied attributes. 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
