a vulnerability,
not a feature.

VibeCheck is the security scanner built for the vibe coder generation. Paste your code. Get an exploit-path report with specific fixes. Large scans can take a few minutes.

No signup. One payment scans up to 10 files. VibeCheck never retains your code or report.

02 · How it works

Three moves. One report.

01
Paste a file

Paste code or upload up to 10 files, 200,000 characters total. Repository scanning is not available yet.

02
The Engine runs

VibeScan uses a proprietary detection prompt to check five layers of AI-specific failure modes that traditional scanners often skip.

03
Get a report

See severity, evidence, exploit paths, and fix recommendations. VibeCheck does not retain your source code or report, so save the results before you leave.

Findings · 3

userId is taken directly from the request body, never compared to the authenticated session user.

const { priceId, userId } = await req.json();
const { data: user } = await supabase
  .from('users').select('*').eq('id', userId).single();
Exploit path

1. Attacker signs up. 2. Captures any other user's id. 3. POSTs { priceId, userId: victimId }. The victim's email is sent to Stripe and the victim's card is charged.

Fix

Drop userId from body. Read from session: const { data: { user } } = await supabase.auth.getUser();

04 · Built for AI code, not legacy code

Legacy scanners were built for human-written code.
They miss what AI ships.
