Stronger Frontend Security Headers

Stashlify Team

Stashlify now sends a stricter set of frontend security headers, including a stronger CSP baseline and tighter browser isolation defaults.

Stashlify’s frontend now ships with a stronger browser security baseline to better protect merchants and staff while keeping the app compatible with existing embeds and public pages.

What changed

  • Added more restrictive security headers for browser behavior and cross-origin handling
  • Strengthened the default Content Security Policy baseline
  • Tightened resource and frame rules while preserving required integrations

This update is focused on reducing avoidable browser-side risk without changing the day-to-day product workflow for stores using Stashlify.
