CVE-2026-34411 — Appsmith versions prior to 1.98 expose sensitive instance management API endpoints without authentication

Medium CVSS 6.9

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.

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
