What it is

Appsmith versions prior to 1.98 expose sensitive instance management API endpoints without authentication. Unauthenticated attackers can query endpoints like /api/v1/consolidated-api/view and /api/v1/tenants/current to retrieve configuration metadata, license information, and unsalted SHA-256 hashes of admin email domains for reconnaissance and targeted attack planning.
