Official Description
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.
Technical Analysis
CVE-2026-34411 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
