Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.31% for the current model date.

Compensating controls

  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs SAP SE SAP NetWeaver Visual Composer and falls inside the recorded affected range.
  2. Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 3 daysRemediation target: Within 90 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

ENISA EUVD identifier

EUVD-2026-98192

No EUVD known-exploited evidence

SAP NetWeaver Visual Composer does not perform sufficient authorization checks in certain portal functionality. An attacker with low privileges could invoke internal operations on a preconfigured remote system. Depending on the remote connection configuration, this could lead to a full compromise of the remote system. This results in a high impact on confidentiality, integrity and availability.

01

What, why and how

SAP NetWeaver Visual Composer does not perform sufficient authorization checks in certain portal functionality. An attacker with low privileges could invoke internal operations on a preconfigured remote system. Depending on the remote connection configuration, this could lead to a full compromise of the remote system. This results in a high impact on confidentiality, integrity and availability.

What

SAP NetWeaver Visual Composer does not perform sufficient authorization checks in certain portal functionality. An attacker with low privileges could invoke internal operations on a preconfigured remote system. Depending on the remote connection configuration, this could lead to a full compromise of the remote system. This results in a high impact on confidentiality, integrity and availability.

Why

The product provides an Applications Programming Interface (API) or similar interface for interaction with external actors, but the interface includes a dangerous method or function that is not properly restricted.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path

CWE-749 ↗

CWE-749: Exposed Dangerous Method or Function. The product provides an Applications Programming Interface (API) or similar interface for interaction with external actors, but the interface includes a dangerous method or function that is not properly restricted.
