Detection Guidance

Check if the Payments for Hubtel plugin version is below 1.0.2.

Use commands like 'curl -s http://[your-site]/wp-content/plugins/payments-for-hubtel/debug.log' to access the log and verify if it contains plain text API credentials.

Additionally, inspect server access logs for unusual requests to the debug log file or plugin directories. Tools like 'grep' can help search for exposed credentials in logs.
