by using mb_strtolower() function with UTF-32LE encoding leads to potential code execution
In PHP versions 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while using the mb_strtolower() function with UTF-32LE encoding, certain invalid strings could cause PHP to overwrite a stack-allocated buffer. This could lead to memory corruption, crashes, and potentially code execution.
Upgrade to 7.3.16 or above, or 7.4.4 or above.
