Summary

Unvalidated data passed to unserialize()

Description

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.

Severity

We consider this vulnerability to be moderately severe.
