Church Admin <= 4.1.17 is vulnerable to Stored Cross Site Scripting (XSS) vulnerability

The Church Admin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘meta-text’ parameter in versions up to, and including, 4.1.17 due to insufficient input sanitization and output escaping. 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.
