Root Cause Analysis
The vulnerability stemmed from insufficient access controls in two key areas:
- The Plugin's boot method enabled debugbar functionality with only a basic backend auth check, not granular permissions.
- The underlying debugbar implementation (from Barryvdh) exposed sensitive data endpoints without OctoberCMS permission integration. The patch added permission checks in both the Plugin's workflow (via registerPermissions) and replaced the third-party ServiceProvider with a customized version implementing permission gates. The confidence is high for the Plugin::boot method (explicitly modified in the commit) and medium for the third-party ServiceProvider (implied by its replacement).
