Confirmed impact

The exposure window ran from February 3 to April 20, 2026. Lovable said private projects and Lovable Cloud were not affected.

Evidence classification

Confirmed real-world incident. High: Lovable published the timeline, affected scope, root cause, and response in a first-party incident report.

Remediation and status

Lovable fixed the regression within two hours of the April 20 report, made current projects private except templates, and changed vulnerability-report triage.

Sentrail analysis

The incident concerns editor/project visibility, not automatic exposure of a deployed website. Builders should still avoid placing secrets in project source and should review project visibility separately from application authorization.

What builders can learn

  • Treat project visibility and deployed-site access as separate controls.
  • Keep credentials out of browser code and repository history.
  • Re-test authorization after backend access-control changes.

Update history
