📝 LLM Analysis

🔸 Vulnerability Description

The code uses window.postMessage with a wildcard (*) as the targetOrigin, which can allow any origin to receive the message. Additionally, it does not validate the origin of incoming messages, which can lead to accepting messages from potentially malicious sources.

🔸 Recommended Fix

Specify a strict targetOrigin instead of * when using postMessage. Additionally, validate the origin of incoming messages to ensure they are from trusted sources.

🔸 Additional Notes

The targetOrigin is set to window.location.origin to ensure that messages are only sent to the same origin. The event listener for message now checks that the origin of the message matches window.location.origin, ensuring that only messages from the same origin are processed. This change helps prevent cross-origin attacks.

🛠 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.
