📝 LLM Analysis

🔸 Vulnerability Description

The code contains hardcoded secrets, specifically a private key that is used for cryptographic operations. Hardcoding secrets in source code is a security risk as it can lead to unauthorized access if the source code is exposed.

🔸 Recommended Fix

Remove the hardcoded private key from the source code. Instead, use a secure method to generate or retrieve the private key at runtime, such as from an environment variable or a secure vault.

🔸 Additional Notes

Ensure that the environment variable PRIVATE_KEY is securely set and managed in the deployment environment to prevent unauthorized access.

🧩 SAST Analysis Summary

Line	Type	Level
22	InsufficientPostmessageValidation	💡 NOTE
29	TooPermissiveCorsPostMessage	⚠️ WARNING

📝 LLM Analysis

🔸 Vulnerability Description

The code uses postMessage with a wildcard "*" for targetOrigin, which can allow malicious parties to intercept messages. Additionally, the origin of incoming messages is not validated, allowing any site to send messages to this window.

🔸 Recommended Fix

Specify an exact targetOrigin for postMessage and validate the origin of incoming messages to ensure they come from trusted sources.

🔸 Additional Notes

Ensure to replace 'https://trusted-origin.com' with the actual origin you expect to communicate with. This change will help prevent unauthorized access and ensure that only messages from trusted sources are processed.

3. src/services/preview.service.js

🧩 SAST Analysis Summary

Line	Type	Level
31	InsufficientPostmessageValidation	💡 NOTE

📝 LLM Analysis

🔸 Vulnerability Description

The code listens for messages from other windows using window.addEventListener('message', ...) but does not validate the origin of the message sender. This can allow any site to send messages to this window, potentially leading to security issues if the messages are not properly validated.

🔸 Recommended Fix

Validate the origin of the message sender to ensure it matches an expected origin before processing the message.

🔸 Additional Notes

Ensure to replace 'https://trusted-origin.com' with the actual origin you expect to receive messages from. This change ensures that only messages from the specified trusted origin are processed, mitigating the risk of processing malicious messages.

4. src/components/superprovider/index.js

🧩 SAST Analysis Summary

Line	Type	Level
36	TooPermissiveCorsPostMessage	⚠️ WARNING
78	TooPermissiveCorsPostMessage	⚠️ WARNING

📝 LLM Analysis

🔸 Vulnerability Description

The code uses postMessage with a wildcard "*" for the targetOrigin, which can allow any origin to receive the message. This could enable malicious parties to intercept or manipulate the message.

🔸 Recommended Fix

Replace the wildcard "*" with a specific, trusted origin that matches the expected domain of the iframe content.

🔸 Additional Notes

Ensure that https://trusted-origin.com is replaced with the actual, trusted origin that matches the domain of the iframe content. This change enhances security by ensuring that only messages from the specified origin are processed.
