⚠️ Potential issue | 🟡 Minor

Validation doesn't reject empty proposals after trimming.

The validation only counts commas but doesn't verify that trimmed proposals are non-empty. Input like "proposal1, , , proposal2" or " , , " would pass validation but result in empty proposal strings.

Filter and validate trimmed proposals.

🔎 Proposed fix 
 const isFormValid = () => {
-    return proposals.split(',').length >= 2;
+    const trimmedProposals = proposals.split(',').map(p => p.trim()).filter(p => p.length > 0);
+    return trimmedProposals.length >= 2;
 };

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
const isFormValid = () => {
if(proposals < 2)
return false;
return true;
}
return proposals.split(',').length >= 2;
};
const isFormValid = () => {
const trimmedProposals = proposals.split(',').map(p => p.trim()).filter(p => p.length > 0);
return trimmedProposals.length >= 2;
};
🤖 Prompt for AI Agents 
In anonymousVoting/clientAnonymousVoting/src/components/CreateProcessPage.js
around lines 64 to 66, the isFormValid function currently counts commas and can
treat empty or whitespace-only entries as valid; change the validation to split
proposals on commas, map over parts and trim each one, filter out any empty
strings, and then require that the resulting array has length >= 2 so only
non-empty trimmed proposals count as valid.

let proposals = input.split(',');

⚠️ Potential issue | 🟠 Major

Security: Avoid debug=True and binding to all interfaces in production.

Running Flask with debug=True enables the interactive debugger, which can execute arbitrary code. Combined with host="0.0.0.0", this exposes the debugger to the network.

Proposed fix using environment variables 
+import os
+
 if __name__ == '__main__':
-    app.run(host="0.0.0.0", port=5000,debug=True)
+    debug_mode = os.environ.get("FLASK_DEBUG", "false").lower() == "true"
+    host = os.environ.get("FLASK_HOST", "127.0.0.1")
+    port = int(os.environ.get("FLASK_PORT", 5000))
+    app.run(host=host, port=port, debug=debug_mode)

🤖 Prompt for AI Agents 
In chatbot/app.py around lines 89-90, running Flask with debug=True and
host="0.0.0.0" is unsafe for production; change the startup to read an
environment/config flag (e.g., FLASK_ENV or APP_ENV) and only set debug=True and
open bind when that flag equals "development"; otherwise set debug=False and
bind to 127.0.0.1 (or better, do not call app.run at all in production and run
under a WSGI server like gunicorn/uwsgi). Ensure the environment-controlled
logic avoids exposing the interactive debugger and restricting network exposure
in non-development environments.
