# SAP NetWeaver: missing authorization checks let low-privilege users run code

Link for people: https://infrastack.ai/live/CVE-2026-109795 (this .md is for agents)

SAP NetWeaver lacks necessary authorization checks and input validation in certain remote-enabled functionality. An attacker with low privileges can send crafted input over a remote interface to execute arbitrary code on the affected system.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:S4CRM affected 204, 205, 206 fixed no fixed version listed
- vendor:S4CEXT affected 107, 108, 109 fixed no fixed version listed
- vendor:BBPCRM affected 713, 714 fixed no fixed version listed

## How to check

Per the CVE record mirror, check whether you run SAP CRM components S4CRM 204/205/206, S4CEXT 107/108/109 or BBPCRM 713/714 (SAP GUI: System > Status > Component information, or transaction SPAM/SAINT). Then open SAP Note 3834842 on me.sap.com to confirm affected support packages and the correction.

## Fix

Apply the correction in SAP Security Note 3834842 (me.sap.com/notes/3834842). Exact support package levels not read.

Affected components from a CVE-list mirror (HOL) only: S4CRM 204-206, S4CEXT 107-109, BBPCRM 713-714. Nothing verified. Fix is SAP note 3834842 (no component versions known).

## From the sources

SAP NetWeaver does not perform necessary authorization checks and lacks sufficient input validation in certain remote-enabled functionality. An attacker with low privileges could send specially crafted input through a remote interface to inject and execute arbitrary code within the affected system. Successful exploitation could extend the attacker's reach beyond the vulnerable component, resulting in a high impact on confidentiality, integrity and availability.
