Overview

AI description

Automated description summarized from trusted sources.

CVE-2024-58136 is a vulnerability in Yii 2, a PHP framework, affecting versions prior to 2.0.52. It involves mishandling the attaching of behavior that is defined by an `__class` array key. This vulnerability is a regression of a previously patched issue, CVE-2024-4990. The vulnerability allows attackers to manipulate the behavior of Yii 2 web applications. It stems from improper type and configuration checks in Yii's use of PHP's `__set()` magic method and the `Yii::createObject()` function, potentially leading to the instantiation of arbitrary PHP classes with malicious arguments. This vulnerability was actively exploited between February and April 2025.

Description: Yii 2 before 2.0.52 mishandles the attaching of behavior that is defined by an __class array key, a CVE-2024-4990 regression, as exploited in the wild in February through April 2025.
