The Smart Custom Fields plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 5.0.7. This is due to insufficient input sanitization and output escaping of uploaded image attachment titles. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. NOTE: This vulnerability was partially patched in 5.0.7.
