Cursor Security Checklist for AI-Built Apps

Why This Matters Now

AI coding tools reduce the cost of producing code. They do not automatically reduce the cost of proving that code is safe. In practice, teams often generate more application logic, more dependencies, more configuration, and more pull requests than before. If security review does not adapt, the backlog grows.

The common risks are predictable: missing authorization checks, unsafe parsing, injection sinks, weak security headers, permissive CORS, secrets in examples, unreviewed dependencies, and configuration that works locally but fails in production. These issues are not new. AI simply makes it easier to produce them at scale.

A modern workflow needs to catch issues early, explain them clearly, and help developers make reviewable fixes. That is the role of an AI security copilot.

What AI Should and Should Not Do

AI is helpful when the problem is bounded and the output can be reviewed. It can explain why a vulnerability matters, summarize impact, recommend a fix, produce verification steps, and sometimes generate a patch preview from trusted source context.

AI should not silently change production code. It should not invent file paths. It should not pretend that a DNS or TLS issue has a source-code patch when the relevant configuration is unknown. It should not auto-merge pull requests.

The safest pattern is staged:

1. 1Scan the website, app, or pull request.
2. 2Explain the finding in developer-friendly language.
3. 3Generate a fix plan.
4. 4Preview a patch only when trusted source context exists.
5. 5Create a GitHub pull request only after explicit approval.
6. 6Require human review before merge.

That workflow turns AI from a risky autopilot into a useful copilot.

Practical Security Controls

Use this checklist when reviewing AI-assisted development work:

• Never paste real production secrets into prompts.
• Keep generated changes small enough to review.
• Require authentication and authorization checks for sensitive routes.
• Validate user input before parsing, rendering, or executing it.
• Avoid dynamic evaluation and unsafe command construction.
• Use parameterized database queries.
• Review new dependencies before merging.
• Run secret scanning on every pull request.
• Run SAST or code-pattern scanning for injection and XSS.
• Run website scanning for headers, TLS, cookies, DNS, and email security.
• Compare PR findings against the main branch baseline.
• Use fix plans and patch previews to speed remediation.
• Require human review before merging AI-generated fixes.

This checklist is intentionally practical. It is meant for teams that need repeatable habits, not a 90-page policy document.

Where Scanners Still Matter

AI is not a replacement for deterministic scanning. Scanners provide evidence. They identify missing headers, weak TLS, exposed secrets, vulnerable dependencies, unsafe code patterns, and pull request regressions. AI becomes useful after that evidence exists.

For example, a scanner can detect a dangerous sink in a file. AI can explain why the pattern matters, propose a safer alternative, and generate a patch preview. But the scanner provides the initial signal and the rerun confirms whether the issue is fixed.

Website and Configuration Findings

Not every finding should become a code diff. Website and configuration findings often require a DNS record, a hosting setting, a reverse proxy change, or a framework configuration update. If the tool does not have trusted source context for the exact file, guidance is safer than a fake patch.

Examples include SPF, DKIM, DMARC, CAA, DNSSEC, TLS certificates, HSTS, CSP, Referrer-Policy, and Permissions-Policy. ZeriFlow can explain these findings and provide configuration guidance. It should only generate a patch when it can safely resolve the relevant source context.

This is why a clear distinction between guidance and diff matters. A user should understand when ZeriFlow is proposing a code change and when it is giving implementation steps.

Pull Requests as the Remediation Boundary

The pull request is a good safety boundary. It gives developers a diff, a discussion thread, CI checks, and a review process. AI-generated fixes should land there, not directly in production.

A good AI-generated security PR should include:

• Finding summary
• Risk and severity
• File changed
• Confidence score and reason
• Verification steps
• A reminder to review before merging

That metadata helps reviewers understand the intent before they inspect the code. It also creates an audit trail for why the change exists.

How ZeriFlow Helps

ZeriFlow is designed around the path from finding to fix. It scans websites and pull requests, separates new findings from existing baseline issues, and gives developers AI-assisted remediation options.

The workflow looks like this:

1. 1Finding detected: ZeriFlow identifies a website, configuration, dependency, secret, or code issue.
2. 2Explain with AI: The developer gets a plain-language explanation of risk and impact.
3. 3Fix with AI: ZeriFlow produces a remediation plan with verification steps.
4. 4Patch Preview: When trusted source context exists, ZeriFlow shows a proposed single-file diff.
5. 5Create GitHub PR: For supported CI findings and eligible plans, ZeriFlow creates a reviewable PR.

This keeps the human in control while reducing the time between detection and remediation.

Adoption Plan

Start with visibility before enforcement. Run scans on your main site and repositories. Establish a baseline. Then enable PR comments and fail only on new critical, high, secret, or high-impact findings.

After developers trust the findings, introduce AI explanations and fix plans. Once the team is comfortable reviewing generated guidance, enable patch previews for supported CI findings. Finally, use GitHub fix PR creation for high-confidence single-file changes.

This sequence avoids the classic mistake of turning on a noisy gate before the team believes the output.

FAQ

Can AI fully automate security fixes?

Only in narrow cases with trusted source context, high confidence, and human review. Most teams should use AI to prepare fixes, not silently merge them.

Can AI generate GitHub pull requests?

Yes, when the tool can verify ownership, repository context, file path, patch confidence, and source context. The PR should still require human review before merge.

Should website scan findings produce code patches?

Usually not unless the exact source configuration is known. DNS, TLS, email authentication, and header findings often need guidance rather than a fake diff.

How do baseline-aware scans help?

They prevent existing legacy warnings from blocking unrelated PRs while still failing new critical, high, secret, or high-impact issues.

What is the safest first step?

Start with scanning and AI explanations. Add fix plans next, then patch previews, then reviewable PR creation for supported CI findings.

Schema Data

Additional Implementation Notes

A useful security workflow should be boring in the best way: repeatable, visible, and reviewable. The team should know where findings come from, why a gate passed or failed, and what changed after remediation. When adopting Cursor-built app security, avoid treating tool output as a final answer. Treat it as structured evidence for engineering review. That keeps the process fast without removing accountability.
