The main security issue in this scenario is the transmission of credentials in cleartext over HTTPS. Even though HTTPS provides a secure transport layer, the credentials should still be protected, such as by using secrets or encryption. Additionally, setting logging to debug and potentially exposing these credentials in logs is also a security concern. Cleartext Credentials: Sending credentials in cleartext within the webhook payload can expose them if HTTPS is not configured correctly or if intercepted by an attacker. Debug Logging: Enabling debug logging can expose sensitive information, including credentials, in logs. Option B highlights the risk of transmitting credentials unencrypted over HTTPS, which can lead to credential leakage. Reference: Cisco DevNet Documentation: Secure Coding Practices
