could use this vulnerability to execute a cross-site scripting (XSS) attack
via a crafted URL. (CVE-2018-7260)

attacker could use this vulnerability to execute an SQL injection attack
via a specially crafted database name. (CVE-2019-11768)

It was discovered that phpmyadmin incorrectly handled some requests. An
attacker could possibly use this to perform a CSRF attack. (CVE-2019-12616)
