To fix the uncontrolled format string issue, we need to ensure that the pattern used in string.Format is safe and does not contain any unexpected format specifiers. One way to achieve this is by validating or sanitizing the path before using it to construct the pattern. Additionally, we can use a safer method to construct the pattern string.

The best way to fix the problem without changing existing functionality is to use a predefined format string and ensure that the path does not contain any format specifiers. We can achieve this by escaping any curly braces in the path before constructing the pattern.
