front/src/components/Admin/Download.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code dynamically creates a URL and appends an anchor element to the document body using unsanitized data from a remote resource. This can lead to DOM-based Cross-Site Scripting (DOMXSS) if the data is manipulated to include malicious scripts.
🔸 Recommended Fix
Sanitize the JSON data before creating the Blob and URL. Ensure that the data does not contain any executable scripts or harmful content.
🔸 Additional Notes
By replacing
<and>with their Unicode escape sequences, we prevent any potential script tags from being executed, mitigating the risk of DOMXSS.2.
front/src/components/Admin/DownloadXML.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code is vulnerable to DOM-based Cross-Site Scripting (DOMXSS) because it appends a dynamically created link element to the DOM using unsanitized data from a remote resource.
🔸 Recommended Fix
Use
textContentto safely set the text of the link element instead of usinginnerHTMLor directly appending unsanitized data.🔸 Additional Notes
The code now ensures that the dynamically created link is removed from the DOM after it is used, which is a good practice to prevent unnecessary elements from lingering in the DOM.

front/src/components/Modals/Recommendations.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code is vulnerable to DOM-based Cross-Site Scripting (DOMXSS) because it directly uses unsanitized data from the
itemListstate to set thesrcattribute of animgelement.🔸 Recommended Fix
Sanitize the
srcattribute by ensuring it only accepts valid URLs and does not execute any scripts.🔸 Additional Notes
The fix ensures that only valid URLs starting with "http" or "https" are used for the
srcattribute of theimgelement. This prevents the execution of any scripts that could be injected through thecoverPhotofield.4.
front/src/components/Searching/Auctions.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code is vulnerable to DOM-based Cross-Site Scripting (DOMXSS) because it directly uses a
useStatevalue (value.coverPhoto) in thesrcattribute of animgtag without any sanitization.🔸 Recommended Fix
Validate and sanitize the
coverPhotoURL before using it in thesrcattribute of theimgtag to ensure it is a safe and valid URL.🔸 Additional Notes
The fix ensures that only URLs starting with 'http' are used in the
srcattribute, mitigating the risk of XSS attacks by preventing potentially harmful scripts from being executed.5.
front/src/components/Searching/FilterCategories.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code contains a DOM-based Cross-Site Scripting (DOMXSS) vulnerability. Unsanitized input from a React
useStatevalue is used in constructing thesrcattribute of animgtag, which can be exploited to execute arbitrary scripts.🔸 Recommended Fix
Sanitize the
srcattribute of theimgtag to ensure that it only contains safe and expected URLs.🔸 Additional Notes
The
encodeURIfunction is used to ensure that thesrcattribute is properly encoded, mitigating the risk of XSS by preventing the injection of malicious scripts.6.
front/src/pages/Profile.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code is vulnerable to DOM-based Cross-Site Scripting (DOMXSS) because it directly uses a value from the
useStatehook (value.coverPhoto) in animgtag'ssrcattribute without any sanitization. This allows an attacker to inject malicious scripts if they can control thecoverPhotovalue.🔸 Recommended Fix
Sanitize the
coverPhotovalue before using it in thesrcattribute of theimgtag to ensure it is a safe URL.🔸 Additional Notes
The
encodeURIfunction is used to ensure that thecoverPhotovalue is properly encoded as a URI, which helps prevent XSS by ensuring that any special characters in the URL are safely encoded.7.
api/index.js🧩 SAST Analysis Summary
📝 LLM Analysis
8.
api/middlewares/Authent.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code contains a hardcoded secret key used for verifying JSON Web Tokens (JWTs). This is a security risk because if the source code is exposed, the secret key can be easily compromised.
🔸 Recommended Fix
Store the secret key in an environment variable instead of hardcoding it in the source code. This makes it more secure and easier to manage across different environments.
🔸 Additional Notes
Ensure that the environment variable
JWT_SECRETis properly set in the environment where the application is running. This can be done using a.envfile or through the hosting environment's configuration settings.9.
api/routes/Users.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
Hardcoded secret is used as a cipher key in
jsonwebtoken.sign. This can lead to security issues if the secret is exposed.🔸 Recommended Fix
Use an environment variable to store the secret key instead of hardcoding it in the source code.
Vulnerability Description: No rate limiting is implemented for the login route.
Potential Risk: Attackers can perform brute force attacks to guess user passwords.
Recommended Fix: Implement a rate-limiting middleware to limit the number of login attempts from a single IP address.
Vulnerability Description: The loop iterating over
userListin the/approveroute is vulnerable to a Denial-of-Service (DoS) attack ifuserListis not properly validated.Potential Risk: An attacker could manipulate
userListto have a very large length, causing the server to hang or crash.Recommended Fix: Validate
userListto ensure it is an array and has a reasonable length before processing.🔸 Additional Notes
Ensure that the environment variable
JWT_SECRETis set in your production environment to maintain the security of your application. The rate limiter is set to allow 5 login attempts per 15 minutes, which can be adjusted based on your security requirements.10.
api/routes/Items.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code performs a file system operation within an endpoint handler without implementing a rate-limiting mechanism. This can lead to Denial-of-Service (DoS) attacks if an attacker exploits this vulnerability by making excessive requests.
🔸 Recommended Fix
Implement a rate-limiting middleware such as
express-rate-limitto restrict the number of requests that can be made to this endpoint within a given timeframe.🔸 Additional Notes
The rate limiter is set to allow a maximum of 10 requests per 15 minutes. This can be adjusted based on the expected traffic and server capacity.
11.
api/routes/Photos.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code lacks rate limiting for an endpoint that performs a file system operation (
fs.unlink), which could be exploited to perform a Denial-of-Service (DoS) attack. Additionally, the input from HTTP parameters is unsanitized, leading to a potential Path Traversal vulnerability, allowing an attacker to delete arbitrary files.🔸 Recommended Fix
Implement rate limiting using a middleware like
express-rate-limitto prevent DoS attacks. Sanitize the input used in file operations to prevent Path Traversal.🔸 Additional Notes
The
path.basename()function is used to sanitize the file path, preventing Path Traversal by ensuring only the file name is extracted. Theexpress-rate-limitmiddleware is applied to the DELETE endpoint to prevent excessive requests.🛠 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.
