DescriptionCVE.org

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.

AnalysisAI

Appsmith versions prior to 1.98 allow unauthenticated remote attackers to access sensitive instance management API endpoints (/api/v1/consolidated-api/view, /api/v1/tenants/current) without authentication, enabling disclosure of configuration metadata, license information, and unsalted SHA-256 hashes of admin email domains. This authentication bypass facilitates reconnaissance for targeted follow-up attacks against Appsmith deployments and their administrators. …

Vulnerability AssessmentAI

Risk Assessment	CVSS 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) reflects low-complexity remote unauthenticated access with confidentiality impact but no integrity or availability impact, consistent with information disclosure. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An attacker performs network scanning or passive reconnaissance to identify publicly exposed Appsmith instances. Upon discovery, the attacker makes unauthenticated HTTP requests to /api/v1/tenants/current and /api/v1/consolidated-api/view, receiving unprotected configuration and licensing metadata without providing credentials. …
Remediation	Upgrade Appsmith to version 1.98 or later to apply the vendor-released patch. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI
