Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Steven Soehl WP-Revive Adserver allows Stored XSS.This issue affects WP-Revive Adserver: from n/a through 2.2.1.

The WP-Revive Adserver plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'wprevive_async' shortcode in all versions up to, and including, 2.2.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for 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.
