Hello,
The phpMyAdmin team is announcing that we are preparing a security fix which we plan to release Friday, tomorrow, approximately 20-24 hours from now.
The attack vector requires the attacker to have login access or be able to trick a victim who has access to a database server. Both the 4.9 and 5.0 branches will be updated.
This announcement is part of our ongoing effort to announce security releases in advance, when available, and should not be interpreted as any commentary on the details or severity of any specific vulnerability.
If you have questions or concerns, you can reach me directly or contact the security team at security@phpmyadmin.net.
Isaac for the phpMyAdmin team
