Almost every page selling a vibe coding security audit opens the same way: a wall of percentages. 85% of apps affected by this, 91% exposed to that. None of them arrive with a sample size, a methodology, or a single finding you could check. The numbers are doing sales work.
I audit vibe-coded apps for a living, so I have the version of those numbers with the denominators still attached. Between June and July 2026 I ran 26 real apps through the same AxonBuild audit: 21 built by other people, plus five of my own production apps, because a method you won’t point at yourself isn’t a method.
The short version: 22 of the 26 had at least one confirmed critical, and not one app, including my own, came out green. Four came back without a single critical. And in 3 of the 21 third-party apps, scanners flagged 33 to 44 known CVEs of which exactly zero were reachable. The last two are the sentences no page selling an audit will print.
What is a vibe coding security audit?
A vibe coding security audit is a code-level review of an AI-built app that verifies which of its protections actually work, not just which ones exist, before real users, data, and money depend on it.
The “vibe coding” part earns its place in the name: apps built with prompt-based tools fail in a specific, recurring catalog (auth middleware that’s written but never mounted, payment state the browser gets to decide, rate limiting defined in the codebase and wired in nowhere), failures a generic penetration test isn’t tuned to look for.
One distinction is worth stating plainly, because most of the market blurs it. My audit engine is automated; I then verify every finding against the code before it reaches a report. Automation is how you cover a whole codebase; verification is how you avoid reporting things that aren’t true. Skip the first and the audit is slow and partial. Skip the second and it’s a scanner with a consulting fee.
The numbers audit sites show you
Spend ten minutes reading pages that sell these audits and you’ll meet a recurring character: the undenominated percentage. Some large share of apps is “affected.” Every app the vendor has “ever tested” harbors something critical. None of it comes with a count, a cohort, or a method, and (this is the tell) none of it ever reports a clean result. A number that can’t be checked is an ad with a percent sign.
The incentive is structural: a service claiming 91% of everyone is vulnerable never has to be right, because nobody can check. Honest audit data has four properties: a denominator, a described cohort, a method you could argue with, and results that sometimes come back clean. If the clean results never appear, you’re reading a funnel, not research.
Here’s mine, held to that standard.
What 26 real audits found
Scores ranged from 29 to 81 out of 100, mean 52. 22 of the 26 apps were red, meaning at least one confirmed-critical finding: exploitable, and verified against the code rather than pattern-matched. The other four were amber: no landmines, a long list of unfinished engineering. Zero were green.
The 29 was a medical-advice app storing patient data in plaintext. The 81 was a thin freelancer dashboard whose only failures were completion gaps, and even it wasn’t ready to take real traffic unwatched. My own five scored 36 to 63, all red. That’s uncomfortable to publish, which is the point: the bar doesn’t bend for whoever’s paying.
Volume tells the same story. Across the 21 third-party apps, the audit confirmed 958 findings (about 46 per app), of which only 58 were critical. Most of what’s wrong with a vibe-coded app doesn’t matter this quarter. Knowing which 6% does is the entire job.
What vibe code actually gets wrong (rarely the keys)
The stereotype says AI-built apps leak API keys. Secrets was actually the best-scoring pillar across the 21 third-party audits, at 84 out of 100: most vibe-coded apps keep their keys in environment variables. When secrets fail it’s severe (6 of 21 apps shipped a real one, three permanently into git history), but it’s the exception.
The worst pillar was Reliability, at 31. At least 23 of the 26 apps had zero working automated tests, including one whose checkout “test suite” never executed the actual checkout code. 17 of 21 recorded errors nowhere, and 12 of the 14 apps with an AI feature had a confirmed denial-of-wallet path: a stranger or a free account could burn the owner’s AI bill without limit.
Vibe code mostly ships untested, unmonitored, and unpatched, the same blind spot that lets a vibe-coded checkout leak money six different ways.
Scanner vs. audit: the 33–44 CVEs that weren’t real
Here’s the finding that best separates a real audit from an automated report. In 3 of the 21 third-party audits, dependency scanners flagged between 33 and 44 known CVEs: pages of red, the kind of output that sells remediation retainers. I traced every one. Reachable from the app: zero. All three reports said so in writing: your scanner is crying wolf, upgrade on your own schedule.
One of those three was the highest-scoring app in the corpus, and its report was no different: a wall of advisories, and not one of them proved reachable once I traced it.
The inverse is just as real. 9 of the 26 apps ran a framework version with a publicly known, reachable RCE or auth bypass, the kind of ship-stopper a single package bump would have closed. Same scanner output, opposite verdicts. Triage is the product.
The same test applies to the do-it-yourself route. As of mid-July 2026, the top results for this exact search are DIY resources rather than services: a builder sharing the audit prompt he ran on his own app, and a 30-point audit skill for coding agents. Both are worth running, since a structured prompt will surface real problems and it costs you an afternoon. What neither can tell you is which of its findings are true. A prompt can flag; only verification can confirm, and no ranking DIY resource publishes what happens when its output meets a human check.
Mine did get that check. When I validated the engine on 10 apps it had never seen, every reported finding survived human verification: zero false positives, recall 1.0 against human-verified ground truth. That’s the number to demand from anyone whose report you’re about to act on, me included.
What a real vibe coding security audit must include, and what it costs
Whether a page calls it a vibe coding security review or an audit, the label matters less than the deliverable. Hold it to this list:
- Evidence per finding: the file and line, plus the mechanism (how it’s exploited, what it costs you) spelled out in plain English.
- An explicit attempt to refute each finding before it’s reported. Anything that survives is confirmed; anything that doesn’t gets dropped, not padded in.
- Severity tied to reachability in your app, never to a scanner’s generic score.
- Coverage beyond security: an app can be unhackable and still lose a customer’s data to a delete you can’t undo. A review that stops at vulnerabilities misses the pillar that fails hardest.
- Both verdicts available: “this gates your launch” and “you’re fine here.” A report with no clean rows was written before your code was opened.
- A rebuild-versus-complete verdict from someone who earns the same fee either way.
Price mostly tracks positioning; evidence discipline is what you’re actually buying, and the list above is how you check for it. It’s how you check me, too. What the Beyond the Demo Audit hands you is that list made literal: Confirmed Findings pinned to file:line, an attempted refutation behind every one, plain-English priorities, and a rebuild-versus-complete call, at a fixed $500 in 48 hours.
An audit answers the security slice of a bigger question, whether the app is actually ready to launch, and if you’re not sure you need the evidence-grade answer yet, the free two-minute scorecard will tell you which of the twelve readiness areas is weakest.
Common questions about vibe coding security audits
How much does a vibe coding security audit cost?
The market runs from a published $1,500 quick audit to quote-after-a-call, with formal penetration testing priced for companies that have a security budget line, not a founder with a live app. The Beyond the Demo Audit runs a fixed $500 in 48 hours.
Do I need a vibe coding security audit before launch?
Timing turns on stakes rather than the calendar. A prototype nobody depends on yet can live on the free DIY resources above. The audit earns its fee once something real is on the line: paying customers, sensitive data, an investor asking due-diligence questions. 22 of 26 working apps in this corpus carried at least one confirmed critical. Working and verified are different claims.
What should a vibe coding security audit include?
At minimum: evidence pinned to file and line, an explicit attempt to refute each finding before it’s reported, severity tied to reachability rather than a scanner’s generic score, and a rebuild-versus-complete verdict from someone who earns the same fee either way. The report should clear an app as readily as it flags one.
An audit seller who only ever finds catastrophe is indistinguishable from a fear number with an invoice attached. The one worth paying for is the one you’d believe on the day it says you’re fine.
