Upgrade Debian:12 phpmyadmin to version 4:4.6.4+dfsg1-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream phpmyadmin package and not the phpmyadmin package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
An issue was discovered in phpMyAdmin. Some data is passed to the PHP unserialize() function without verification that it's valid serialized data. The unserialization can result in code execution because of the interaction with object instantiation and autoloading. All 4.6.x versions (prior to 4.6.4), 4.4.x versions (prior to 4.4.15.8), and 4.0.x versions (prior to 4.0.10.17) are affected.
