Security Fixes Suggested via Pull Request – Powered by Autofic 🛠️ Hello, My name is Jeongmin Oh, a software engineer from South Korea 🇰🇷 working on AI-powered security solutions. We recently developed a tool called Autofic, which scans public code repositories for potential vulnerabilities using SAST tools and provides automated remediation using an LLM-based model. 🔐 During a recent analysis of your repository, our system flagged some areas that may pose security risks. To assist, we’ve submitted a Pull Request with proposed patches generated by Autofic. Please feel free to take a look when convenient. If you have any questions or would like to understand more about how Autofic works, don’t hesitate to reach out. Thank you for your attention and for maintaining such valuable open-source work. Best regards, |

app.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The session middleware settings in the code are using default configurations which lack specific security attributes. These include the absence of
domain,expires,httpOnly,path,secure, and a custom session cookie name, which are crucial for securing session cookies.🔸 Recommended Fix
Set the
domain,expires,httpOnly,path, andsecureattributes for the session cookies. Also, use a custom session cookie name to enhance security.🔸 Additional Notes
Make sure to replace
'yourdomain.com'with the actual domain of your application. Adjust theexpirestime as necessary for your application's requirements.2.
public/ckeditor/plugins/wsc/dialogs/wsc.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code uses the
window.postMessage()API with a wildcard"*"as the target origin. This allows any origin to receive the message, which can lead to information disclosure.🔸 Recommended Fix
Specify a more restrictive origin instead of
"*". This should be the exact origin of the intended recipient of the message.🔸 Additional Notes
Make sure to replace
"https://trusted-origin.com"with the actual trusted origin that should receive the messages. This change ensures that only the specified origin can receive the messages, mitigating the risk of information disclosure.3.
routers/addcontest.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code directly writes user-defined input to the
Responseobject without proper escaping, which can lead to a Cross-Site Scripting (XSS) vulnerability. This occurs when rendering user input in theres.renderfunction without ensuring the input is properly sanitized or escaped.🔸 Recommended Fix
Ensure that all user-defined inputs are properly sanitized or escaped before being rendered in the response. Use a library or function that automatically escapes HTML entities to prevent XSS attacks.
🔸 Additional Notes
The
Comm.escapeHTMLfunction is assumed to be a utility function that properly escapes HTML entities to prevent XSS attacks. If such a function does not exist, it should be implemented to ensure all user inputs are sanitized before rendering.4.
routers/problem.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code directly sends user-defined input in the response object without proper escaping, which can lead to Cross-Site Scripting (XSS) vulnerabilities.
🔸 Recommended Fix
Use
res.render()with a template engine that automatically escapes HTML to safely render user input.🔸 Additional Notes
The modification ensures that user input is properly escaped before being rendered in the response, thus mitigating the risk of XSS attacks.
🛠 Fix Summary
