Hi @corydolphin

In this PR I've used Python's repr method to escape special characters and print them as ordinary characters as a bugfix for CVE-2024-1681 - https://nvd.nist.gov/vuln/detail/CVE-2024-1681.

This should resolve #349.

### GitHub Vulnerability Alerts

#### [CVE-2024-1681](https://nvd.nist.gov/vuln/detail/CVE-2024-1681)

corydolphin/flask-cors is vulnerable to log injection when the log level
is set to debug. An attacker can inject fake log entries into the log
file by sending a specially crafted GET request containing a CRLF
sequence in the request path. This vulnerability allows attackers to
corrupt log files, potentially covering tracks of other attacks,
confusing log post-processing tools, and forging log entries. The issue
is due to improper output neutralization for logs.
