🔐 Summary of Security Fixes
Overview
example/image-event/src/index.jsexample/image/src/index.jsexample/web/src/app.js1.
example/image-event/src/index.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The Express application is currently exposing the
X-Powered-Byheader, which reveals information about the underlying framework being used (Express). This can provide attackers with useful information for targeting specific vulnerabilities.🔸 Recommended Fix
Disable the
X-Powered-Byheader by settingapp.disable('x-powered-by'). Alternatively, consider using the Helmet middleware to handle this and other security-related headers.🔸 Additional Notes
Disabling the
X-Powered-Byheader is a simple yet effective way to reduce the amount of information exposed to potential attackers. For a more comprehensive approach to securing HTTP headers, consider using the Helmet middleware, which can handle this and other security-related headers.2.

📝 LLM Analysis
🔸 Vulnerability Description
The Express application is exposing the
X-Powered-Byheader, which reveals information about the server's framework.🔸 Recommended Fix
Disable the
X-Powered-Byheader by settingapp.disable('x-powered-by').🔸 Additional Notes
Disabling the
X-Powered-Byheader is a simple yet effective way to enhance the security of an Express application by not disclosing unnecessary information about the server's technology stack.3.

📝 LLM Analysis
🔸 Vulnerability Description
The Express application exposes the
X-Powered-Byheader by default, which reveals information about the server technology being used. This can be leveraged by attackers to exploit known vulnerabilities in specific versions of the framework.🔸 Recommended Fix
Disable the
X-Powered-Byheader by settingapp.disable('x-powered-by'). Alternatively, using the Helmet middleware can provide a more comprehensive security enhancement.🔸 Additional Notes
Disabling the
X-Powered-Byheader is a simple yet effective way to obscure server information. For enhanced security, consider using additional middleware like Helmet, which can help secure Express apps by setting various HTTP headers.🛠 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.
