Descriptions

Cross-site scripting vulnerability in Advanced Custom Fields versions 6.1.0 to 6.1.7 and Advanced Custom Fields Pro versions 6.1.0 to 6.1.7 allows a remote authenticated attacker to execute an arbitrary script on the web browser of the user who is logging in to the product with the administrative privilege.

The Advanced Custom Fields plugin for WordPress is vulnerable to Stored Cross-Site Scripting via ACF post type and taxonomy labels in versions 6.1 to 6.1.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
