Unvalidated data passed to unserialize()
A vulnerability was reported where some data is passed to the PHP
unserialize() function without verification that it's valid serialized data.
Due to how the PHP function operates,
Unserialization can result in code being loaded and executed due to object instantiation and autoloading, and a malicious user may be able to exploit this.
Therefore, a malicious user may be able to manipulate the stored data in a way to exploit this weakness.
We consider this vulnerability to be moderately severe.
All 4.6.x versions (prior to 4.6.4), 4.4.x versions (prior to 126.96.36.199), and 4.0.x versions (prior to 188.8.131.52) are affected
Upgrade to phpMyAdmin 4.6.4, 184.108.40.206, or 220.127.116.11 or newer or apply patch listed below.
