Vibe Leak Index

Version 1.0 · Updated 2026-04-21 · CC BY 4.0

A compilation of third-party security research and industry estimates on security exposure in publicly-reachable AI-built apps — Lovable, Bolt, Replit, and v0 deployments — covering leaked credentials, missing Supabase Row-Level Security, missing Content-Security-Policy headers, and client-bundle dependencies with known High or Critical CVEs. These are landscape estimates, not a first-party Securie scan.

How these classes are measured

The estimates compiled here come from public security research and vendor reports on AI-built apps. The underlying studies typically measure four exposure classes against publicly-reachable Lovable, Bolt, Replit, and v0 deployments — apps gated behind authentication are out of scope. Each check is a request a curious engineer could run by hand:

  • Leaked credentials — the deployed JS bundle is fetched and matched for known credential prefixes (sk-, sk_live_, AKIA, eyJhbG, Supabase service-role JWTs, etc.) plus high-entropy candidate strings. A hit counts only after the value is confirmed to match the expected credential format and is not a public test fixture.
  • Supabase RLS — for an app whose bundle references a Supabase URL + anon key, the OpenAPI spec exposed at /rest/v1/ is enumerated and an unauthenticated SELECT * read is attempted against each table with the anon key. A successful read with no policy filter indicates RLS disabled. Failed reads, policy-scoped reads, and 401/403 responses indicate RLS enforced.
  • Content-Security-Policy — a single HTTP HEAD request against the deployed root URL; presence/absence of a Content-Security-Policy response header.
  • Vulnerable client-bundle dependencies — the deployed JS bundle is parsed for module names and pinned versions, then cross-referenced against the NPM advisory database for High or Critical CVEs.

Limitations

  • Selection bias. The sample is publicly-reachable apps. Apps gated behind a login wall on the index page, served on private subdomains, or in unfinished states were excluded. The true rate across all AI-built apps may be higher (private apps are typically less hardened than public-facing ones) or lower (private apps may sit behind defense-in-depth a public scan can’t see).
  • Point-in-time. Each estimate reflects a point-in-time view from the underlying research. Apps fix issues; apps break new ones. The figures are updated as newer research becomes available; the current values are at /api/data/stats.json.
  • Credential-detection precision. Pattern matching for sk-, AKIA, etc. catches the obvious-shape secrets. High-entropy unprefixed secrets carry a higher false-positive risk and are typically counted only after a second-stage confirmation step.
  • RLS measurement is one query type. The underlying research tests unauthenticated reads. Apps that block unauthenticated reads but allow authenticated cross-tenant reads (BOLA / IDOR patterns inside RLS policy) are counted as RLS-enforced here; those are detected by Securie’s Login & Access Safety check at scan time, not by this index.
  • Vulnerable-dep counts include transitive. The ~47% rate is “at least one” H/C-severity CVE anywhere in the parsed client bundle. Most are non-exploitable in the app’s actual usage; the rate is a hardening signal, not an exploit count.
  • The index does not name affected apps. These are aggregate landscape estimates only; no individual app is named.

Reproducibility

These figures are landscape estimates drawn from public research. A reviewer who wants to verify a single number can run the same checks — fetch the client bundle, match credential prefixes, enumerate the Supabase OpenAPI spec, cross-reference dependency CVEs — against an independently-collected sample of publicly-reachable AI-built apps, and should land in the same range if their sample composition is comparable.
