Advanced Custom Fields: Font Awesome Field < 6.0.0 - Authenticated (Contributor+) Stored Cross-Site Scripting

Description

The Advanced Custom Fields: Font Awesome Field plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 5.0.2 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.
