Platform Security Guides
Platform-by-platform security guides for AI builders and no-code tools · what each platform secures for you, what it leaves exposed, and how to fix it.
- CVE-2025-48757 Explained: How to Check If Your Lovable App Is Affected · CVE-2025-48757 let attackers bypass authentication in Lovable apps that relied on client-side login state without database-level enforcement · tables lacking RLS policies could be read directly. The scaffolding has been patched, but existing apps must verify the fix: enable RLS on every user-data table, validate sessions server-side, and audit data access patterns.
- How to Secure Your Lovable App: A Complete Guide · 63% of AI-built apps ship with at least one critical vulnerability. For Lovable apps the biggest risks are missing RLS policies, a service-role key in frontend code, exposed API keys, open storage buckets, vulnerable dependencies, and auth bypass. Fix each in your Supabase dashboard, then verify with a 30-second SimplyScan scan.
- Is Vibe Coding Safe? Security Risks of AI-Generated Code · Vibe coding is safe only with a security layer the AI doesn't provide: in scans of 500+ AI-built apps, 63% shipped a critical vulnerability, 41% exposed API keys in client code, and 38% had broken access control. Prompt for security explicitly, review generated code, and scan every app before it ships.
- Cursor App Security Checklist: 10 Things to Check Before You Ship · Before shipping a Cursor-built app, verify 10 things: no hardcoded secrets, RLS policies on every table, auth guards on every route, server-side authorization, input validation, safe error messages, patched dependencies, security headers, restricted CORS, and proper token storage. Cursor optimizes for working code, so these checks consistently fail without review.
- Bolt.new Security Guide: 7 Vulnerabilities to Fix Before Launch · Bolt.new apps ship with predictable flaws: API keys bundled into client JavaScript, Supabase tables with RLS enabled but no real policies, routes without authentication, exposed service-role keys, vulnerable npm packages, client-side authorization, and missing security headers. Fix secrets and auth first, then verify RLS scopes to auth.uid().
- Windsurf Security Guide: Securing AI-Flow Generated Apps · Windsurf's AI-Flow generates working code fast, but it optimizes for function, not safety. The seven most common gaps are hardcoded credentials, missing input validation, wildcard CORS, client-side security logic, insecure session storage, leaky error handling, and absent security headers. Fix each with server-side enforcement and environment variables, then scan the deployed app.
- Replit Security Guide: Protecting Your Deployed Repl · Deployed Repls are public the moment you hit Deploy, and the most common failures are hardcoded secrets, missing route authentication, exposed database credentials, no rate limiting, wildcard CORS, outdated dependencies, and sensitive console logs. Move secrets to Replit's Secrets manager, add auth middleware, and scan before shipping.
- Security Guide for Bolt, Windsurf & Replit Apps · Bolt.new, Windsurf, and Replit apps share the same core vulnerabilities: API keys in client-side code, missing authentication, no input validation, and over-privileged database access. Fix them by moving secrets server-side, adding auth before deploying, validating every input, and using minimum-privilege credentials · then verify with an automated scan.
- Security Guide for No-Code Apps: Bubble, WeWeb, FlutterFlow & Xano · No-code apps on Bubble, WeWeb, FlutterFlow, and Xano are only as secure as their configuration: security features are opt-in, not automatic. Enforce data access rules at the backend (privacy rules, Firebase rules, API authentication), keep API keys server-side, restrict CORS, and never treat client-side visibility conditions as security.
- Base44 Security Guide: Critical Vulnerabilities and How to Protect Your App · Base44 generates working full-stack apps, but scans consistently find exposed API keys in client code, missing authentication and authorization, database tables without access policies, XSS in user content, no rate limiting, and insecure sessions. Fix the top three first: remove client-side secrets, add auth guards, and enable row-level security.
- v0 Security Guide: Is Vercel's AI Code Generator Secure? · v0 generates clean React and Next.js UI code, but it ships no authentication, input validation, or error handling · those are your responsibility. The biggest risks are publicly accessible pages, hardcoded placeholder credentials, and unvalidated form input. Add auth guards, move secrets to environment variables, validate every input, and scan the deployed app before launch.
- Bubble Security Guide: Privacy Rules, API Tokens, and Data Exposure · Without privacy rules, every record in a Bubble app's database is publicly readable through the Data API, even for logged-out visitors. Secure your app by adding privacy rules to every data type, protecting API tokens (they grant full admin access), authenticating backend workflows, and password-protecting the version-test environment.
- FlutterFlow Security Guide: Firebase Rules, Auth, and Data Protection · FlutterFlow apps inherit their security from Firebase, and the defaults ship wide open: permissive Firestore rules let anyone read or modify your database with just your project ID. Replace allow-all rules with ownership checks, enable App Check, restrict API keys, lock down Storage uploads, and validate input server-side before launch.
- WeWeb Security Guide: XSS, API Protection, and Frontend Risks · WeWeb requires unsafe-eval and unsafe-inline in its Content Security Policy, so XSS is a higher risk than in traditional frameworks. Secure it by proxying third-party API calls through Xano or Supabase Edge Functions, keeping secret keys out of Collections, filtering data server-side instead of in the browser, and sanitizing user content on the backend.
- Xano Security Guide: API Authentication, RBAC, and Backend Protection · Xano ships enterprise-grade security · AES-256, SOC 2, JWT auth, RBAC, rate limiting · but most of it is opt-in. New API endpoints are callable by anyone until you enable authentication per API group. Priorities: turn on auth everywhere, use auth.id instead of user_id inputs to stop IDOR attacks, and lock CORS to your frontend domain.
- Raydian Security Guide: AI-Generated App Risks and Best Practices · Raydian apps inherit the risks of AI-generated code: studies find 30-62% of it contains security flaws. The five biggest issues are inherited anti-patterns, missing server-side validation, insecure default configurations, exposed API keys, and authorization gaps. Fix authentication, move secrets to environment variables, validate inputs server-side, then scan before launch.
- Is Lovable Safe? Security Risks You Should Know in 2026 · Lovable is safe as a platform: managed infrastructure, built-in authentication, and server-side secrets handling. The real risks live in the generated code · missing Row-Level Security policies, client-side-only authorization, hardcoded API keys, and skipped server-side validation. Enable RLS on every table, move secrets to server functions, and scan before launch.
- Is Cursor Safe? What Developers Need to Know in 2026 · Cursor is safe to use as an editor, but its generated code needs the same review as human code: expect hardcoded API keys, string-concatenated SQL queries, client-only auth checks, and leaky error messages. An eight-point review checklist plus secret scanning and npm audit catches the issues before they ship.
- Is Bolt.new Safe? Security Analysis for 2026 · Bolt.new is safe to use, but its generated apps ship as prototypes: expect API keys in frontend code, database tables without row-level security, missing server-side validation, and absent security headers. Fix those four before handling real user data · a 15 to 30 minute post-generation checklist covers the most damaging gaps.
- Is Replit Safe? Security Risks for Deployed Apps in 2026 · Replit itself is safe: isolated containers and a managed deployment pipeline. The dangers are inside your project · hardcoded secrets in public Repls, frontend env variables shipped to the browser, and AI-generated code without validation, rate limiting, or authorization. Make your Repl private, move every key to the Secrets panel, and scan the deployed app.
- Is Windsurf Safe? Security Risks of AI-Flow Coding in 2026 · Windsurf is a safe tool: code stays local, changes show in your git diff, and generated architecture is clean. The risks are in the output · authentication without authorization, dev defaults like open CORS and verbose errors deployed to production, and vulnerable dependencies. Review each generation, add authorization, and scan before deploying.
- React Security Checklist: 10 Vulnerabilities to Fix Before Launch · React apps run entirely in the browser, so every bundled secret, VITE_ variable, and route guard is visible to users. Real security means keeping API keys server-side, sanitizing HTML with DOMPurify before dangerouslySetInnerHTML, validating user URLs, auditing npm dependencies, and enforcing authentication on the server for every sensitive call.
- Next.js Security Guide: Securing Your AI-Generated Application · Secure a Next.js app by shaping server component data before it serializes to the client, adding auth checks and input validation to every API route and Server Action, keeping secrets out of NEXT_PUBLIC_ variables, setting security headers via middleware, adding CSRF protection, and validating file uploads server-side.
- Bolt.new vs Lovable vs Cursor: Which Produces the Most Secure Code? · Lovable produces the most secure code out of the box because it generates RLS policies and complete auth flows by default · Cursor is safest for experienced developers who specify security requirements · Bolt.new needs the most hardening. All three optimize for functionality over security, so every AI-built app still needs a security review before production.
- 60 Free Security & Developer Tools Every Vibe Coder Should Bookmark · Sixty free, no-signup tools cover the security gaps AI app generators leave behind: live checks for SSL, security headers, DNS, CORS, and exposed .env files, browser-local utilities like a JWT debugger and secret scanner, plus generators, converters, and SEO and AI visibility checks. Each takes seconds · run the live checks after every deploy.
- Is v0.dev Safe? What Vercel's AI Builder Does and Doesn't Secure · v0.dev is safe as a platform · Vercel runs the hosting and preview infrastructure securely. The generated React code is the risk: dangerouslySetInnerHTML XSS vectors, secret keys in client components, no Content Security Policy, and unvalidated API input. Treat every component as a first draft, audit the client boundary, and scan before launch.
- Is Base44 Safe? A Security Review of the AI App Builder · Yes, Base44 is safe to build on · hosting, auth, and infrastructure are professionally managed, especially since the Wix acquisition. Real leaks come from your app's configuration: over-permissive entity access rules, full-record API responses, and API keys pasted into frontend code. All three are yours to fix, and an afternoon covers it.
- Is Bubble Safe? What Privacy Rules Actually Protect · and What They Don't · Yes, Bubble is safe · it is the most mature no-code platform, and its infrastructure is professionally run. The catch: privacy rules are opt-in per data type. Skip them and the Data API plus client-side searches will hand entire tables to anyone who asks. Set them on every type and Bubble apps are genuinely secure.
- Is FlutterFlow Safe? Your Firebase Rules Are the Real Attack Surface · Yes, FlutterFlow is safe · the builder and platform are not the weak point. Your Firebase security rules are: a FlutterFlow app is exactly as secure as the rules on its Firestore database and storage buckets, and the most common failure is shipping test-mode rules that let anyone read and write everything.
- Windsurf vs Cursor: Which AI IDE Writes More Secure Code? · Neither IDE writes safer code: both run the same frontier models, so Windsurf and Cursor produce the same classes of vulnerabilities. They fail differently · Windsurf's Cascade ships one big unreviewed diff, Cursor accumulates a thousand small accepted edits. Your review gate, rules files, and a post-deploy scan matter more than the tool choice.
- Vibe Coding Guardrails · How to Let AI Write Code Without Getting Burned · Vibe coding guardrails are fixed rules you set before AI writes any code: never hardcode API keys, enable Row-Level Security on every table, validate all input server-side, and keep secrets in environment variables. Enforce them with project-level instructions, security prompts after each feature, and an automated scan before every deploy.
