fix: Regular expression injection

[odaysec]

fix vulnerable in #247

To fix the problem, we need to sanitize the user input before using it to construct the regular expression. The best way to do this is by using the _.escapeRegExp function from the lodash library, which escapes special characters in the input string. This ensures that the user cannot insert characters that have special meaning in regular expressions.

1. Install the lodash package if it is not already installed.
2. Import the lodash library in the file.
3. Use the _.escapeRegExp function to sanitize the config.exclude_regex before constructing the regular expression.
