- Also known as: GHSA-955M-RR6M-2F9V
- Severity: CVSS 9.4 (Critical), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 4.0.3, 3.9.7, 2.7.7, 1.18.4
- Published: 2026-09-08 · Updated: 2026-09-08

## Affected

- SAP\_SE SAP Cloud Application Programming Model (CAP): through 2.7.6; through 3.9.6; through 4.0.2
- @sap/cds-mtxs (npm): from 4.0.1, fixed in 4.0.3
- @sap/cds-mtxs (npm): from 3.0.1, fixed in 3.9.7
- @sap/cds-mtxs (npm): from 2.0.2, fixed in 2.7.7
- @sap/cds-mtxs (npm): fixed in 1.18.4

## 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.

## What to do

- Check your stack: if you ship or depend on SAP\_SE SAP Cloud Application Programming Model (CAP), @sap/cds-mtxs, upgrade to a fixed version (4.0.3, 3.9.7, 2.7.7, 1.18.4) per the references below.
