Summary
Snipe-IT before 8.7.0 fails to properly gate Laravel Passport's OAuth client management routes, allowing any authenticated user to register OAuth clients with attacker-controlled redirect URIs. Attackers can trick administrators into approving consent screens, then exchange authorization codes for bearer tokens inheriting full admin API permissions lasting up to 40 years.
