Lovable Errors: Every Documented Failure and Fix
Errors in Lovable apps and their Supabase backends: error loops, RLS misfires, broken auth, lost backends.
Lovable stuck in an error loop: 'Try to Fix' keeps failing
Stop clicking Try to Fix after the second failed attempt. Revert to the last working version from Lovable's history, then switch t...
Moderate · 30-90 minutesLovable Supabase RLS not enabled: anyone can read your app's data (CVE-2025-48757)
Warning: this is a live data exposure, not a bug. In the Supabase dashboard, run Security Advisor to find every table with RLS off...

Documented Lovable incidents
Someone finally scanned 380,000 vibe-coded apps. About 5,000 were leaking medical records and bank financials.
In May 2026, Israeli cybersecurity startup RedAccess reported scanning roughly 380,000 apps built on platforms including Lovable, Base44, Replit, and Netlify. Thousands sat on the open web with no access controls, about 5,000 were actively leaking sensitive information, and roughly 40% of the vulnerable apps exposed data like medical records, bank financials, and customer chat logs. The most common root cause was a default-public setting nobody ever flipped.
Lovable's third strike: a free account and five API calls opened other tenants' code and credentials
On April 20, 2026, security researcher @weezerOSINT disclosed a Broken Object Level Authorization (BOLA) flaw in Lovable that let any free account access other tenants' profiles, source code, database credentials, AI chat history, and customer data in as few as five API calls, with projects created before November 2025 broadly exposed. The bug was reported to Lovable on March 3, 2026, and sat unfixed for 48 days; Lovable shipped a fix about two hours after public disclosure. It was the company's third major security incident in about thirteen months.
1 in 10 scanned Lovable apps would hand your data to anyone who asked the database directly
On May 29, 2025, Semafor reported research showing that of 1,645 web apps built with Lovable, 170 (about 10 percent) let anyone access sensitive data: names, email addresses, financial information, and secret API keys for services like Stripe, Google Maps, and Gemini. The cause was architectural: Lovable-generated apps queried Supabase directly from the browser with a public anon key and relied entirely on Row Level Security policies that were often missing or misconfigured. The pattern was assigned CVE-2025-48757.
VibeScamming: Guardio Asked Lovable to Phish, and Lovable Delivered the Whole Kit
In April 2025, Guardio Labs published a benchmark called VibeScamming that tested how easily AI tools could be talked into building a phishing campaign. Lovable performed worst by a wide margin: from simple prompts it generated near-perfect replicas of real login pages including Microsoft's, deployed them live on deceptive subdomains, and even built admin dashboards to track the stolen credentials. ChatGPT mostly refused; Claude resisted until 'security research' framing wore it down.
