Impacted is confidentiality, integrity, and availability. CVE summarizes:

The Advanced Members for ACF plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the create_crop function in all versions up to, and including, 1.2.5.

The vulnerability was partially patched in version 1.2.5.
