Secure Vibe Coding: A Pre-Launch Checklist with Tests
A practical release gate for AI-built apps: test tenant boundaries, inspect credentials and dependencies, check the deployed site, and record what remains unverified.
· 6 min read
Before shipping an AI-built app, review its repository, deployed website, and authenticated workflows separately. The most useful release question is specific: can a user read another customer's data, expose a credential, or trigger an action they should not control? A working demo does not answer those questions.
This guide includes a small reproducible lab and a release worksheet. The lab uses synthetic data and demonstrates authorization mistakes; it does not scan your application or measure CyberLens detection accuracy. The workflow applies whether code was written by an assistant, a person, or both.
Start with a release evidence sheet
Record the commit, deployment URL, test date, tester, and result for each check below. Use a staging environment you control and disposable accounts. Keep real customer records and credentials out of screenshots and reports. A failed check needs an owner; an untested check should remain visibly untested.
| Surface | Check | Evidence to keep |
|---|---|---|
| Repository | Credentials, dependency changes, install scripts, risky input handling | Reviewed commit and specific files |
| Public website | HTTPS, response headers, exposed debug output, redirects | Observed URL and response |
| Authenticated application | Object ownership, tenant boundaries, roles, privileged actions | Account roles and request outcomes |
| Builder and agent tools | Workspace, execution, browser and network access | Effective runtime configuration and dummy-data tests |
Run a small authorization lab
Download and inspect the educational Node.js test file, save it as security-boundaries.test.mjs, then run it with Node.js 22 or newer:
node --test security-boundaries.test.mjsNo dependencies or installation are required. The file does not open network connections, read application files, execute a shell, or use real credentials. Its twelve tests cover three educational models. The four tests beginning tenant: are the relevant section here.
The fixture gives Alice a private report in team A and Bob an account in team B. A deliberately vulnerable function accepts either signed-in user. The corrected model requires the same tenant and either ownership or a tenant-administrator role. Tests also reject unauthenticated access, missing resources, another ordinary member, and an administrator from a different tenant.
// Simplified teaching model: principal is already server-verified.
principal.tenant === report.tenant &&
(principal.id === report.owner || principal.role === 'tenant-admin')A passing test suite is expected: one test explicitly proves that the vulnerable example permits the wrong access, then proves that the corrected model denies it. This is not production middleware. Your application may require different roles, sharing rules, or database policies; test those actual rules at the boundary where requests are handled.
Apply the lesson to your real API
Create two test tenants and private records in each. Sign in as Alice, record a permitted request, then request Alice's record as Bob. Repeat for updates, deletion, exports, file downloads, and any background task that accepts an object identifier. Test a same-tenant user without permission as well as a different-tenant user.
Do not trust a tenant ID or role sent by the browser as proof of authority. Derive identity from the verified session and look up the relevant relationship on the server. Confirm denial before reading or changing the protected data. Hiding a button is useful interface behavior, but it is not a server-side permission check. OWASP recommends checking authorization on every request and denying access when no rule permits it.
Check credentials before changing anything else
Review tracked configuration, examples, build output, logs, deployment settings, and repository history for secrets. A browser bundle cannot keep a secret: anything shipped to a browser can be inspected. Distinguish intentionally public identifiers from private service credentials using the provider's documentation.
If a real credential was exposed, revoke or rotate it first, investigate its use, and then remove the exposed copy. Deleting a file from the latest commit does not invalidate credentials or erase previous copies. The OWASP secrets management guidance explains credential lifecycle and rotation considerations. Use placeholders in test fixtures and avoid pasting a real token into an AI conversation to ask whether it is sensitive.
Review inputs, dependencies, and browser controls
Trace important inputs to their destinations: database queries, HTML rendering, file paths, shell commands, and external requests. Validation should match the field's meaning; the protection needed at an HTML sink differs from the protection needed in a SQL query. Review privileged state changes for their own authorization and request-forgery protections.
Inspect manifest and lockfile changes together. Understand why a new dependency exists, where it comes from, and whether its install or runtime behavior affects sensitive data. Reproducible versions help review, but do not prove a package is trustworthy. Record accepted findings and their reason rather than treating every warning as a launch blocker.
Check the deployed site's actual responses for appropriate browser controls and cookie behavior. A Content Security Policy must fit the application; copying an arbitrary policy can break functionality or leave broad exceptions. Headers add protection but cannot repair missing object authorization. Test after deployment because proxy and hosting configuration can differ from development.
Include the tools that built and operate the app
An agent may have access beyond the application repository: a browser session, deployment credentials, an MCP connector, or a shell. Review each capability independently. Keep credentials outside default tool-visible paths and give test workflows dedicated accounts. Read-only access still allows information to be disclosed.
For a focused procedure, use our agent permissions checklist. For unfamiliar packages, use the pre-install skill review. These are different checks from testing the deployed app.
Make a release decision you can explain
Stop a release for an exposed live credential, demonstrated unauthorized access, or another unresolved issue that crosses an important trust boundary. Investigate suspicious execution paths before running them. Prioritize other findings using their actual exposure and impact; a missing header and a confirmed account takeover are not interchangeable.
Start a CyberLens scan for the surfaces it supports, then record its scope alongside your manual checks. A public website scan cannot establish that every authenticated tenant boundary is correct. A clean result is one piece of evidence, not certification that the application is secure.
After a fix, repeat the failed check and a permitted-use check, keep the result with the release, and add a regression test to your project. Re-run the relevant checks when authentication, dependencies, agent permissions, or deployment configuration changes. The secure vibe coding workflow puts this release gate in a broader development process.

Published by CyberLens AI with AI-assisted drafting. The linked educational fixture was run with Node.js 22.22.3 on September 19, 2026: all 12 assertions passed on synthetic examples. This is not a test of your application, a CyberLens detection benchmark, or a claim of independent human security review. Verify guidance against the linked documentation and your installed versions.
