src/extension/contentScript.ts🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code does not validate the origin of the received message in the
window.addEventListenerfunction. This means any site, including potentially malicious ones, can send messages to this window.🔸 Recommended Fix
Add a check to validate the
event.originagainst expected origins before processing the message.🔸 Additional Notes
The fix involves checking the
event.originagainstwindow.location.originto ensure messages are only processed if they originate from the same origin as the current window. This is a minimal and effective way to mitigate the risk of processing messages from untrusted sources.🛠 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.
