What is CVE-2023-47130?

Yii is a renowned open source PHP web framework, widely used for developing web applications. A critical vulnerability exists in Yii versions prior to 1.1.29, where the framework improperly handles the unserialize() function when it processes arbitrary user input. This flaw could be exploited by an attacker to execute arbitrary code on the server, leading to complete system compromise. It is crucial for users of affected versions to upgrade to 1.1.29 or later, as there are no viable workarounds to mitigate this risk.
