Every year, thousands of students register for schools and universities through online platforms. These websites often request a lot of personal information, including:
- Full name
- National ID number
- Email address
- Phone number
- Home address
- Photo
- Grades or academic background
But here’s the big question:
👉 Is our data really safe when we submit it?
🕵️♂️ What I Noticed During My Own Registration
While registering on several school websites in my country, I began to pay closer attention to how these platforms handled student data.
Out of curiosity — and because I’m passionate about cybersecurity — I noticed something alarming:
After completing my registration, I received a receipt with a URL containing a number, something like
id=xxx9. Out of curiosity, I changed that number toxxx8— and to my surprise, the page showed another student’s receipt, with all of their private information visible.
This kind of issue is known as IDOR (Insecure Direct Object Reference). It means that the system does not properly check if a user is allowed to access the data they’re requesting.
No authentication, no permission check, no warning — just access to someone else’s private file.
💣 The Real-World Danger: Your Data Could Be Sold
This kind of flaw might seem small, but it opens the door to mass data leaks.
If this is possible with one or two ID changes, it could easily be automated by a malicious actor. A black hat hacker could write a simple script that goes through thousands of IDs, collecting private student data.
Imagine seeing something like this being sold online:
🧨 “Student database for sale – [My Country] students – X0000+ full profiles”
And all of it collected from a school website that was supposed to protect our personal data.
⚠️ Why This Is a Serious Problem
If any random user can access someone else’s private documents, the risks are huge:
- Identity theft
- Phishing or scams using real data
- Private academic details being exposed
- Misuse of personal photos
- Long-term privacy consequences
And here’s the thing: most students don’t even know their data can be accessed this way. They just fill out forms and upload documents, trusting the system.
🧠 Why These Issues Exist
Unfortunately, many educational platforms in my country are built without basic security practices, such as:
- Proper user access control
- Secure document delivery methods
- Encryption and session validation
- Security testing before launch
In most cases, these platforms are developed quickly to meet registration deadlines — and security is ignored.
✅ What Can Be Done
🏫 For Schools and Developers:
- Follow basic web security practices (like the OWASP Top 10).
- Never allow direct file access without validating the user.
- Use secure tokens or session-based permissions for document downloads.
- Test websites regularly for vulnerabilities before going live.
🎓 For Students:
- Be cautious when submitting personal information online.
- If something feels wrong (like being able to view others’ data), speak up or report it if it’s allowed.
- Avoid uploading unnecessary documents unless required.
- Protect your data — it’s your right.
💬 Final Thoughts
Digital education is a great step forward, but without security, it becomes a risk — not just for institutions, but for every student.
As students, developers, and citizens, we should all ask:
Are we protecting our future, or exposing it?
