Security Fixes Suggested via Pull Request – Powered by Autofic 🛠️ Dear Esteemed Developer, My name is Jeongmin Oh, an undergraduate student majoring in Information Security at Gachon University 🇰🇷. I'm currently participating in a university project focused on enhancing software security using a combination of static analysis (SAST) and large language models (LLMs). As part of this initiative, we developed a tool called Autofic, which analyzes public code repositories to detect security vulnerabilities using SAST tools and then generates suggested fixes with the support of LLMs. 🔐 During a recent analysis of your repository, our system identified a few areas that may pose security risks. To assist in addressing them, we have submitted a Pull Request containing proposed patches automatically generated by Autofic. Since this work is part of an academic research project, your review and potential approval would be immensely valuable to us. 🙏 If you have any questions or would like to learn more about how Autofic works, please don’t hesitate to reach out. Thank you for your time and for your valuable contribution to the open-source community. Best regards, |

🔧 About This Pull Request
This patch was automatically created by AutoFiC,
an open-source framework that combines static analysis tools with AI-driven remediation.
Using Semgrep, CodeQL, and Snyk Code, AutoFiC detected potential security flaws and applied verified fixes.
Each patch includes contextual explanations powered by a large language model to support review and decision-making.
🔐 Summary of Security Fixes
Overview

backend/api/routes/campaign.route.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code is vulnerable to Cross-Site Scripting (XSS) because it directly writes user-defined input to the response object without proper escaping or sanitization. This can allow an attacker to inject malicious scripts into the web page.
🔸 Recommended Fix
To mitigate this vulnerability, ensure that any user-defined input is properly sanitized or escaped before being sent in the response. Use
res.json()to safely send JSON data, which inherently escapes potentially harmful characters.🔸 Additional Notes
The change involves using
res.json()instead ofres.send()for sending JSON responses, which helps in preventing XSS by escaping potentially harmful characters.2.
backend/api/routes/user.route.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code directly writes user input to the response object using
res.send(), which can lead to Cross-Site Scripting (XSS) vulnerabilities if the input is not properly sanitized.🔸 Recommended Fix
Sanitize the user input before sending it in the response to ensure any HTML or script tags are properly escaped.
🔸 Additional Notes
The
escape-htmlpackage is used to sanitize user input before sending it in the response. This ensures that any HTML or script tags are properly escaped, mitigating the risk of XSS attacks.3.
backend/config/secureRoute.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code contains a hard-coded secret key used for verifying JSON Web Tokens (JWTs). Hard-coded secrets can be easily exposed and exploited by attackers.
🔸 Recommended Fix
Replace the hard-coded secret key with an environment variable. This approach keeps the secret out of the source code and allows it to be managed securely.
🔸 Additional Notes
Ensure that the environment variable
JWT_SECRET_KEYis securely set in the environment where the application is running. This can be achieved through configuration management tools or secure environment management practices.4.
frontend/server.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code contains a hard-coded secret for session management, which is a security risk. Additionally, the session middleware is missing several important security configurations, including
domain,expires,httpOnly,path,secure, and a custom session cookie name.🔸 Recommended Fix
Use environment variables to store the session secret. Configure the session middleware with additional security options such as
httpOnly,secure,domain,path,expires, and a custom session cookie name.🔸 Additional Notes
Ensure that
SESSION_SECRETis set in the environment variables in production environments. Adjust themaxAgeanddomainvalues as per your application's requirements. Thesecureflag should be enabled in production to ensure cookies are only sent over HTTPS.🛠 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.
