🧩 SAST Analysis Summary

Line	Type	Level
9	InsufficientPostmessageValidation	💡 NOTE

📝 LLM Analysis

🔸 Vulnerability Description

The code does not validate the origin of the message received by the DiffWorker. This could allow any site, including potentially malicious ones, to send messages to the worker.

🔸 Recommended Fix

Validate the origin of the message in the event listener to ensure it comes from a trusted source.

🔸 Additional Notes

Ensure to replace 'trusted-origin.com' with the actual origin you expect the messages to come from. This change assumes that the worker is intended to receive messages only from a specific trusted origin. If multiple origins are trusted, consider using an array of allowed origins and check if e.origin is included in that array.

🧩 SAST Analysis Summary

Line	Type	Level
4	InsufficientPostmessageValidation	💡 NOTE

📝 LLM Analysis

🔸 Vulnerability Description

The code does not validate the origin of the received message in the message event listener, which can lead to security issues if a malicious site sends a message to this window.

🔸 Recommended Fix

Implement origin checking to ensure that messages are only processed if they come from a trusted source.

🔸 Additional Notes

Ensure that you replace 'https://your-trusted-origin.com' with the actual trusted origin of your application. This change will help prevent messages from untrusted sources from being processed.
