CVE-2026-0506: Missing Authorization check in SAP NetWeaver Application Server ABAP and ABAP Platform

Due to a Missing Authorization Check vulnerability in Application Server ABAP and ABAP Platform, an authenticated attacker could misuse an RFC function to execute form routines (FORMs) in the ABAP system. Successful exploitation could allow the attacker to write or modify data accessible via FORMs and invoke system functionality exposed via FORMs, resulting in a high impact on integrity and availability, while confidentiality remains unaffected.

Security readout for executives and security teams

Plain-English summary

CVE-2026-0506 is a high-severity SAP authorization flaw. A logged-in attacker could misuse an RFC function in SAP NetWeaver AS ABAP or ABAP Platform to run ABAP form routines. This could let them change data or trigger exposed system functions, affecting integrity and availability. The provided sources do not show confidentiality impact or active exploitation.

Executive priority

Prioritize in the next SAP patch cycle, faster for business-critical or broadly integrated ABAP systems. The risk is high because a valid user could alter data or disrupt operations. It is not currently supported by supplied evidence as actively exploited or unauthenticated.

Technical view

The issue is CWE-862, missing authorization check, in SAP NetWeaver Application Server ABAP and ABAP Platform. A network-accessible, authenticated attacker with low privileges can misuse an RFC function to execute FORMs. CVSS 3.1 is 8.1: AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H. Affected SAP_BASIS versions are 700, 701, 702, 731, 740-758, and 816.

Likely exposure

Exposure is most relevant where affected SAP_BASIS releases are deployed and RFC access is reachable by authenticated users or integrated systems. Systems with broad RFC permissions, many technical users, or externally reachable SAP interfaces may face higher operational risk. The source bundle marks other versions as unaffected by default.

Exploitation context

Exploitation requires authentication and does not require user interaction. The attacker abuses an RFC function to invoke FORMs, not a fully unauthenticated remote compromise. CISA KEV status is false in the supplied data, and no cited source confirms active exploitation.

Researcher notes

The key control failure is missing authorization on an RFC path that can execute ABAP FORMs. Analysis should focus on affected SAP_BASIS releases, RFC exposure, and authorization boundaries. Avoid assuming data theft impact; the CVSS vector and description state confidentiality is unaffected.

Mitigation direction

  • Review SAP Note 3688703 for the official correction and prerequisites.
  • Apply relevant SAP Security Patch Day updates for affected SAP_BASIS releases.
  • Restrict RFC access to trusted users and systems where business operations allow.
  • Review technical-user authorizations for unnecessary RFC privileges.
  • Monitor SAP guidance for updated remediation instructions.

Validation and detection

  • Inventory SAP_BASIS release levels across ABAP systems.
  • Confirm whether listed affected versions are present.
  • Check whether SAP Note 3688703 or related corrections are implemented.
  • Review RFC-enabled access paths and assigned user authorizations.
  • Monitor logs for unusual RFC calls involving form routine execution.
