Publication date: 2026-09-08

Last updated on: 2026-09-08

Assigner: SAP SE

Description
@sap/cds-mtxs NPM library does not perform sufficient checks on certain functionality used in multitenant CAP applications with extensibility enabled. An unauthenticated attacker could send specially crafted requests to obtain sensitive credentials and abuse them to replace or delete tenant data. Successful exploitation can result in a high impact on availability and integrity of the application. There may also be partial impact to the confidentiality of business data.

Executive Summary

This vulnerability affects the @sap/cds-mtxs NPM library used in multitenant CAP applications with extensibility enabled. It fails to properly validate requests, allowing unauthenticated attackers to send crafted requests that steal sensitive credentials. These credentials can then be used to replace or delete tenant data, impacting application integrity and availability.

Detection Guidance

To detect this vulnerability, inspect network traffic for unusual requests targeting multitenant CAP applications with extensibility enabled. Check logs for unauthorized access attempts or requests containing sensitive credential patterns. Review application configurations for exposed endpoints related to tenant data manipulation.

Impact Analysis

An attacker could gain unauthorized access to sensitive data, modify or delete critical tenant information, and disrupt application services. This could lead to data breaches, service outages, and potential financial or reputational damage depending on the application's use case.

Compliance Impact

This vulnerability could lead to violations of GDPR (data protection) and HIPAA (health data privacy) due to unauthorized access, modification, or deletion of sensitive data. Organizations may face legal penalties, loss of compliance certifications, and increased scrutiny from regulators.

Mitigation Strategies

Immediately disable extensibility features in multitenant CAP applications if not required. Apply patches or updates from SAP addressing this issue. Restrict network access to application endpoints using firewalls or network segmentation. Monitor for suspicious activity and rotate any exposed credentials.
