Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Due to an OS Command Execution vulnerability in SAP Forecasting & Replenishment, an authenticated attacker with administrative authorizations could abuse a non-remote-enabled function to execute arbitrary operating system commands. Successful exploitation could allow the attacker to read or modify any system data or shut down the system, resulting in a complete compromise of confidentiality, integrity, and availability.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

OS Command Execution vulnerability in SAP Forecasting & Replenishment allows an authenticated attacker with administrative authorizations to execute arbitrary operating system commands through a non-remote-enabled function, enabling complete system compromise including data exfiltration, modification, or shutdown.

MitigationApply SAP security patches for this vulnerability immediately; restrict administrative authorizations to minimum required personnel and review user access controls until patch can be deployed.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify SAP Forecasting & Replenishment is installed
    Access SAP transaction SE11 or SM37 and search for packages or programs related to Forecasting & Replenishment (typically under SAP APO or SCM modules). Use transaction SPAM to view installed software components.
    Affected if The product SAP Forecasting & Replenishment is present in the SAP system
  2. Determine the installed version of SAP Forecasting & Replenishment
    Use transaction SAINT (SAP Add-On Installation Tool) or execute report RS Component Version in SE38 to list installed SAP components and their versions. Compare against any available SAP security notes or version information for this CVE.
    Affected if The installed version falls within the range affected by CVE-2026-34259 (version comparison required)
  3. Review administrative authorizations in the system
    Use transaction SUIM (User Information System) and run the report for roles with SAP_ALL or administrative profiles. Check transaction PFCG for roles assigned to users that include authorization objects S_RFC, S_ADM_SERV, or similar administrative authorizations.
    Affected if Users possess administrative authorizations that can invoke the vulnerable non-remote-enabled function
  4. Identify access to the vulnerable function module
    Use transaction SE37 (Function Builder) to locate function modules within the Forecasting & Replenishment component. Check authorization object S_RFC for access to function groups. Review transaction SU53 after user attempts to identify which functions are being called.
    Affected if The vulnerable function module is accessible to authenticated users with administrative rights
  5. Check for RFC and function module exposure
    Use transaction SM59 (RFC Destinations) to verify if the affected function module has RFC enabled. Use transaction SE37 and check the 'Remote-enabled module' flag. Review transaction SIFP (SAP Interface Directory) if available.
    Affected if The function module is exposed via RFC despite being classified as non-remote-enabled, or is callable by authenticated administrative users

A user is affected if SAP Forecasting & Replenishment is installed with a vulnerable version and an authenticated user with administrative authorizations can access the vulnerable function module.
