As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

An issue was discovered in phpMyAdmin 4.8.x before 4.8.2, in which an attacker can include (view and potentially execute) files on the server. The vulnerability comes from a portion of code where pages are redirected and loaded within phpMyAdmin, and an improper test for whitelisted pages. An attacker must be authenticated, except in the "$cfg['AllowArbitraryServer'] = true" case (where an attacker can specify any host he/she is already in control of, and execute arbitrary code on phpMyAdmin) and the "$cfg['ServerDefault'] = 0" case (which bypasses the login requirement and runs the vulnerable code without any authentication).

The bug was discovered 06/19/2018. The weakness was presented 06/21/2018 (Website). The advisory is shared for download at phpmyadmin.net. This vulnerability was named CVE-2018-12613 since 06/21/2018. The attack can be initiated remotely. A single authentication is needed for exploitation. Technical details are unknown but a public exploit is available.
