src/index.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code directly writes user-defined input to the HTTP response without proper escaping, which can lead to a Cross-Site Scripting (XSS) vulnerability.
🔸 Recommended Fix
Ensure that the output is properly escaped before being sent in the HTTP response. This can be achieved by using a safe method to send the response, such as
res.send()with proper validation.🔸 Additional Notes
The fix ensures that only valid challenges are returned in the response, and an immediate return is added to prevent further execution if the token is valid. This helps mitigate the risk of XSS by ensuring that only expected and validated data is sent in the response.
🛠 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.
