• Packagist phpmyadmin/phpmyadmin: >= 4.0.0, < 4.9.4 → fixed in 4.9.4 • Packagist phpmyadmin/phpmyadmin: >= 5.0.0, < 5.0.1 → fixed in 5.0.1

In phpMyAdmin 4 before 4.9.4 and 5 before 5.0.1, SQL injection exists in the user accounts page. A malicious user could inject custom SQL in place of their own username when creating queries to this page. An attacker must have a valid MySQL account to access the server.
