How I Would Fix database rules leaking customer data in a GoHighLevel founder landing page Using Launch Ready
The symptom is usually simple to spot: a founder notices one visitor can see another visitor's form submission, lead record, or private customer detail on the landing page or in an embedded portal. In business terms, this is not a "bug", it is a data exposure incident that can damage trust, trigger support load, and block launch.
The most likely root cause is weak authorization around the database or API layer, not the landing page itself. If I were inspecting this first, I would check whether the page is pulling records with an overly broad query, whether GoHighLevel custom fields or webhooks are returning more data than needed, and whether any public endpoint is missing ownership checks.
Triage in the First Hour
1. Freeze anything that can expose more data.
- Pause ad traffic, pause webhook automations, and temporarily disable any public page component that reads customer records.
- If there is an embed or custom script on the GoHighLevel page, remove it until I confirm the access path.
2. Inspect recent logs and audit trails.
- Check application logs for requests hitting lead lookup, form submission, webhook handlers, and admin APIs.
- Look for repeated requests from the same IPs, unusual response sizes, and any 200 responses returning multiple customer records.
3. Review the live landing page behavior.
- Open the page in an incognito session.
- Submit test leads with two different emails and confirm whether one session can see data from the other.
- Check mobile and desktop because some leaks only show up in one render path.
4. Inspect GoHighLevel assets and automations.
- Review workflows, triggers, custom values, forms, surveys, snapshots, and embedded scripts.
- Confirm whether any workflow sends full record payloads to a front-end app or stores sensitive fields in a public place.
5. Check deployment and environment settings.
- Verify production environment variables are correct.
- Confirm no test database URL or shared API key is being used in production.
- Review Cloudflare cache rules if the page or API responses are cached publicly.
6. Look at access control assumptions.
- Identify every endpoint that returns customer data.
- Confirm each one checks ownership or tenant scope before returning anything.
7. Capture evidence before changing code.
- Save request samples, screenshots, timestamps, and affected record IDs.
- This helps me prove the fix worked and prevents guesswork later.
A quick diagnostic command I often use during triage is:
curl -i https://your-domain.com/api/lead/123
If that endpoint returns private fields without proving who owns record 123, the problem is almost certainly authorization design rather than UI design.
Root Causes
| Likely cause | What it looks like | How I confirm it | |---|---|---| | Missing ownership check | Any logged-out user can fetch another person's lead data | Inspect API handler logic and compare request identity to record owner ID | | Over-broad database rule | Query returns all rows instead of tenant-scoped rows | Review row-level rules or query filters for missing `user_id` or `account_id` conditions | | Public cache leak | One user's response gets cached and served to another user | Check Cloudflare cache headers and origin response headers | | Misconfigured webhook payloads | Full customer objects are sent into a public front-end state store | Trace webhook destination and inspect stored payloads | | Shared test/prod secrets | Production points at staging data or vice versa | Compare environment variables across deployments | | Weak GoHighLevel automation design | A workflow writes private fields into visible custom values or email templates | Review snapshot exports and workflow steps for exposed fields |
My default assumption is that this is an authorization failure until proven otherwise. UI bugs do not usually leak multiple customers' records by themselves; bad access rules do.
The Fix Plan
1. Stop the leak first.
- Disable any endpoint or automation that returns customer records without checking identity.
- If needed, return a safe error like "data temporarily unavailable" instead of partial private data.
2. Reduce what the landing page can see.
- The founder landing page should only receive the minimum fields required for conversion: name, email status, booking status, or a masked reference ID.
- Do not expose raw notes, internal tags, payment details, phone numbers unless they are essential.
3. Add strict ownership checks.
- Every read path must verify that the current user/session belongs to the record being requested.
- In practice this means matching on authenticated account ID, contact ID, or tenant ID before returning anything.
4. Remove public caching from sensitive endpoints.
- Set private responses to `Cache-Control: no-store`.
- Keep Cloudflare caching only for static assets like images, CSS, JS bundles, and public marketing content.
5. Rebuild any risky automation flows.
- In GoHighLevel workflows, split marketing actions from private data actions.
- Use one workflow for lead capture and another for internal notifications so sensitive fields never need to touch public UI logic.
6. Rotate secrets if there was any chance of exposure.
- Rotate API keys used by forms, webhooks, email providers, analytics tools, and deployment platforms.
- Reissue credentials before re-enabling traffic if logs show unauthorized access attempts.
7. Add safe logging only.
- Log request IDs, route names, status codes, and tenant identifiers where appropriate.
- Never log full payloads containing emails plus private notes unless absolutely necessary for debugging and protected by access controls.
8. Deploy behind a rollback plan.
- I would not merge this directly into live without a reversible release window.
Here is the simplest rule I would enforce:
- Public pages can read public content only.
- Private customer records require authenticated ownership checks every time.
That sounds basic because it is basic. Most leaks happen when teams assume "the page is hidden" means "the data is protected".
Regression Tests Before Redeploy
I would not redeploy until these checks pass:
1. Unauthorized access test
- Open two separate sessions as two different users or test contacts.
- Confirm session A cannot view session B's records by URL guessing or refresh behavior.
2. Empty state test
- If no record exists for a user, show a neutral empty state instead of error details or fallback data from another user.
3. Cache isolation test
- Verify sensitive endpoints return `no-store`.
- Confirm Cloudflare does not cache personalized responses.
4. Workflow test
- Submit forms through GoHighLevel automation and confirm only intended fields reach each destination.
5. Secret handling test
- Confirm no secret appears in front-end code bundles or browser network calls.
- Validate environment variables are present only server-side where required.
6. Negative case test
- Try invalid IDs, expired sessions, malformed requests, and missing auth headers.
- Expected result: 401 or 403 with no leaked metadata.
7. Cross-device test
- Test desktop Safari/Chrome plus mobile Safari/Chrome because auth bugs sometimes appear differently across clients.
8. Acceptance criteria
- Zero unauthorized record reads in testing.
- No sensitive field visible in browser dev tools for anonymous users.
- p95 response time stays under 300 ms for public pages after fixes are applied.
- No regression in form conversion flow above 95 percent successful submission rate during QA runs.
Prevention
I would put guardrails in three layers: security review, monitoring, and release discipline.
- Security guardrails
- Treat every database read as untrusted until ownership is verified.
- Use least privilege on API keys and service accounts.
- Review CORS so only approved origins can call private endpoints.
- Monitoring guardrails
```text Alert if: 1) any sensitive endpoint returns 200 without auth 2) response size spikes above normal by 3x 3) repeated 403s suggest probing 4) cache hits occur on personalized routes ``` These alerts catch leaks early before they become screenshots in support tickets.
- Code review guardrails
- I review behavior first: who can read what data?
- Then I check tests for auth boundaries before style changes or refactors.
-,Every pull request touching leads,,forms,,or webhooks needs one explicit authorization review note.,
- UX guardrails
-,Never show raw internal errors on founder landing pages., -,Use clear loading,,empty,,and denied states so users do not retry broken flows endlessly.,
- Performance guardrails
-,Keep public assets cached aggressively but keep personalized data uncached., -,Measure LCP,,CLS,,and INP after adding security middleware so protection does not break conversion.,
When to Use Launch Ready
This sprint includes:
- DNS setup,
- redirects,
- subdomains,
- Cloudflare configuration,
- SSL,
- caching rules,
- DDoS protection,
- SPF/DKIM/DMARC,
- production deployment,
- environment variables,
- secret handling,
- uptime monitoring,
- handover checklist,
What I need from you before kickoff:
- Domain registrar access,
- Cloudflare access,
- GoHighLevel admin access,
- hosting/deployment access if there is custom code,
- list of integrations like Stripe,,Calendly,,Zapier,,Make,,or email providers,
- current pain points plus screenshots of any leak behavior,
If you already have traffic running,,,I would pause paid ads until we confirm no unauthorized reads are possible.,A broken funnel wastes ad spend fast; a leaked funnel also creates trust damage that costs more to repair than the sprint itself.,
