📝 LLM Analysis

🔸 Vulnerability Description

The code uses postMessage with a target origin of "*", which is too permissive and can allow any malicious site to intercept messages. Additionally, the origin of incoming messages is not validated, allowing any site to send potentially harmful messages.

🔸 Recommended Fix

Specify an exact target origin in postMessage to ensure that messages are only sent to trusted origins. Additionally, validate the origin of incoming messages to ensure they are from trusted sources.

🔸 Additional Notes

The whatsAppUrl is used as the trusted origin for both sending and receiving messages. This ensures that only messages from the specified origin are processed, mitigating the risk of unauthorized message handling.

🛠 Fix Summary

All identified vulnerabilities have been remediated following security best practices such as parameterized queries and proper input validation. Please refer to the diff tab for detailed code changes.
