Summary
The NewsmanApp plugin for WordPress is affected in all versions up to and including 3.7.29. Insufficient sanitization and output escaping of the 'billing_first_name' and 'billing_last_name' parameters allows script injection (CWE-79). An unauthenticated remote attacker can inject arbitrary web scripts into pages that run when a user accesses an injected page. Exploitation requires the Newsman Remarketing feature to be enabled with a non-empty Remarketing ID.

Description from the CNA
The NewsmanApp plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'billing_first_name, billing_last_name' parameter in all versions up to, and including, 3.7.29 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This vulnerability is only exploitable when the Newsman Remarketing feature is enabled and a non-empty Remarketing ID is configured in the plugin settings.
