Tenant-to-global admin escalation via unchecked role assignment
Published Aug 6, 2026 · Updated Aug 6, 2026
Improper privilege management in OpenReception before 1.0.2 allows remote authenticated users to gain platform-wide administration. The staff-update PUT handler authorizes tenant administration, then writes a schema-accepted GLOBAL_ADMIN role without checking the actor's role. TENANT_ADMIN access and reauthentication are required; the resulting account can administer every tenant, although appointment plaintext remains encrypted.
