User data accessible without proper authorization

What does this mean?

Another user could read information belonging to a different account, including email address and billing details.

Affected

GET /api/users/{id}

How to fix it

Works with Cursor, Claude Code, Codex, Lovable

AI makes building easier.
It doesn't make security automatic.

You don't know what to ask

“Make my app secure” isn't a security assessment. Your coding agent only investigates what you tell it to investigate.

Your app is more than its code

Configuration, authentication, APIs, exposed endpoints and the behaviour of your live application can introduce risks that aren't obvious while coding.

Security shouldn't require becoming a security expert

You shouldn't need to understand penetration testing to know whether your users' data is properly protected.

From URL to fixes in 3 steps.

  1. 1

    Add your app

    Enter the URL and confirm you're authorised to have it checked.

  2. 2

    We check it

    VibeGuard independently examines your live application for security weaknesses.

  3. 3

    Fix what matters

    Get plain-English findings and ready-to-use prompts for your AI coding tool.

Don't just find vulnerabilities. Fix them.

Every finding ships with a prompt written for your coding agent. Copy it, paste it, re-scan.

The problem

Broken Access Control

Risk: High

Users may be able to request resources belonging to other accounts by modifying an identifier in an API request.

Ready to fix

Cursor, Claude Code, Codex

Review the authorization logic protecting GET /api/users/:id.

Ensure that the authenticated user can only read their own record, or records they are explicitly allowed to access (for example as a workspace admin).

Add the ownership check on the server side before any database read. Return 404 (not 403) for records the caller is not allowed to see, so ids cannot be enumerated.

Write a test that signs in as user A, requests user B's id, and asserts the request fails.

Copy. Paste. Fix. Re-scan.

We look for the security mistakes that can put your app and users at risk.

Authentication
Can someone get into an account they shouldn't?
Credential handling, password reset, brute-force protection
Authorization
Can users access another user's data?
Object-level and function-level access control
APIs
Are sensitive endpoints exposed or insufficiently protected?
Unauthenticated routes, admin surfaces, mass assignment
Sensitive data
Could private information be unintentionally exposed?
Leaked keys, verbose responses, public storage
Input security
Can malicious input manipulate your application?
Injection, cross-site scripting, unsafe redirects
Configuration
Are unsafe settings exposing unnecessary information or functionality?
Security headers, debug modes, error verbosity
Sessions
Are login sessions handled safely?
Cookie flags, expiry, fixation, logout
Known vulnerabilities
Are exposed components affected by known security issues?
Outdated libraries, servers and frameworks with public advisories

Built your SaaS with AI?

VibeGuard is designed for founders and makers who ship software with AI but aren't security experts. Keep building with the tools you already use. We provide the independent security layer.

We don't replace your coding agent.
We check its work.

User data accessible without proper authorization

Affected
GET /api/users/{id}

What we found

The endpoint returns a full user record for any numeric id, as long as the request carries a valid session for any account.

Why it matters

Another user could read information belonging to a different account, including email address and billing details.

What could happen

A signed-in user increments the id in the URL and downloads the profile of every customer, one request at a time.

How to fix it

Check that the authenticated user is allowed to see the requested record before returning it. Do this on the server, on every request.

Fix with AI

Review the authorization logic protecting GET /api/users/:id.

Ensure that the authenticated user can only read their own record, or records they are explicitly allowed to access (for example as a workspace admin).

Add the ownership check on the server side before any database read. Return 404 (not 403) for records the caller is not allowed to see, so ids cannot be enumerated.

Write a test that signs in as user A, requests user B's id, and asserts the request fails.

Three one-time security checks. Every check includes the same report, fix prompts and one fix verification re-check.

Quick Security Check

€59one-time

A fast security check for important, obvious weaknesses.

Best for early-stage apps and pre-launch checks.

Choose Quick
Recommended

Standard Security Check

€99one-time

A more complete security assessment covering your app's main attack surface.

Best for SaaS products and live applications.

Choose Standard

Deep Security Check

€199one-time

Our most thorough security assessment for complex and production applications.

Best for more complex apps or when you want deeper coverage.

Choose Deep

Every check includes

  • Live web application security check
  • Plain-English security report
  • Severity and prioritisation
  • Evidence for relevant findings
  • Recommended remediation
  • Ready-to-use AI fix prompts
  • Downloadable report
  • One fix verification re-check included

Not sure which one? Standard suits most live SaaS products. You can always buy a deeper check later.

Your app stays yours.

  • We require your authorisation before scanning

  • We don't need your source code

  • We don't modify your application

  • Your findings are private

Questions founders ask before they run a check.

Is AI-generated code secure?

Not by default. AI coding tools write code that works, and they are good at it, but they only protect against the problems you describe to them. Access control, session handling and configuration mistakes are easy to miss because the app looks and behaves correctly. An independent check of the running application catches what the code review conversation never mentioned.

Can I ask Cursor or Claude Code to check my app instead?

You can, and you should. The difference is that your coding agent inspects the code it can see and answers the question you asked. VibeGuard examines the deployed application from the outside, the way an attacker would: it probes endpoints, sessions and configuration without any knowledge of your intentions. The two are complementary. We find the issue, your agent fixes it.

What does VibeGuard actually test?

Authentication, authorization, exposed APIs, sensitive data exposure, input handling, configuration, session management and known vulnerabilities in the components your app exposes. Every check runs against the live application at the URL you verify.

Do you need access to my source code?

No. We test the running application only. Read-only repository access will be offered later as an option for deeper analysis, never as a requirement.

Can VibeGuard modify my website?

No. The check is read-only by design. We do not create, change or delete data in your application, and we do not run destructive tests.

Is this a penetration test?

It is an automated security check with clear, prioritised findings and evidence. It is not a manual penetration test performed by a human specialist, and it does not replace one where a formal assessment is required. For most early-stage products it covers the mistakes that actually put users at risk.

How long does a security check take?

Most checks complete well within an hour. You get an email when the report is ready, and you can keep working in the meantime.

What happens if you find a vulnerability?

Each finding comes with a plain-English explanation, the affected endpoint, the evidence we collected, severity, and a ready-to-use prompt for your AI coding tool. Findings are private to you and are never shared.

Can I use the fix prompts with Cursor, Claude Code or Codex?

Yes. Prompts are written to be pasted directly into any AI coding tool that has access to your codebase. They describe the problem, the expected behaviour and a test to confirm the fix.

Can I re-check my app after fixing the problems?

Yes. One fix verification re-check is included with every security check, whichever depth you choose. After applying the recommended fixes, it re-tests the findings from your original assessment, on the same app, and tells you whether each is resolved, still present or inconclusive. It is not a second full assessment: new features or a different app need a new check.

Is my security report private?

Yes. Reports are visible only to the account that ordered the check. We do not publish, sell or share findings. Aggregated, anonymised statistics may be used for research, never anything that identifies your app.

You built it.
