This release fixes two security vulnerabilities:
PMASA-2019-3 is an SQL injection flaw in the Designer feature
PMASA-2019-4 is a CSRF attack that's possible through the 'cookie' login form
Upgrading is highly recommended for all users. Using the 'http' auth_type instead of 'cookie' can mitigate the CSRF attack.
The solution for the CSRF attack does remove the former functionality to log in directly through URL parameters (as mentioned in FAQ 4.8, such as
https://example.com/phpmyadmin/?pma_username=root&password=foo). Such behavior was discouraged and is now removed. Other query parameters work as expected; only pma_username and pma_password have been removed.
This release also includes fixes for many bugs, including:
Several issues with SYSTEM VERSIONING tables
Fixed json encode error in export
Fixed JavaScript events not activating on input (sql bookmark issue)
Show Designer combo boxes when adding a constraint
Fix edit view
Fixed invalid default value for bit field
Fix several errors relating to GIS data types
Fixed javascript error PMA_messages is not defined
Fixed import XML data with leading zeros
Fixed php notice, added support for 'DELETE HISTORY' table privilege (MariaDB >= 10.3.4)
Fixed MySQL 8.0.0 issues with GIS display
Fixed "Server charset" in "Database server" tab showing wrong information
Fixed can not copy user on Percona Server 5.7
Updated sql-parser to version 4.3.2, which fixes several parsing and linting problems
There are many, many more bug fixes thanks to the efforts of our developers, Google Summer of Code applicants, and other contributors.
