CVE-2026-89107— Code Injection vulnerability in SAP S/4HANA (Manage Substitution/Validation Rules)

Quick assessment

Affected
SAP_SE SAP S/4HANA (Manage Substitution/Validation Rules)
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

SAP S/4HANA 的“管理替代/验证规则”功能在利用特定领域脚本语言的规则定义功能处理输入时，未能进行充分的输入验证。具有特定业务权限的经过身份验证的攻击者可以提交精心构造的输入内容，规则处理逻辑会将其解释为可执行的 ABAP 代码。成功利用此漏洞可使攻击者在系统中执行任意 ABAP 代码，从而导致受影响系统被完全接管，并对系统的机密性、完整性和可用性造成严重影响。

Vulnerability Title
Code Injection vulnerability in SAP S/4HANA (Manage Substitution/Validation Rules)
Source: CVE Program / CVE List V5
Vulnerability Description
SAP S/4HANA (Manage Substitution/Validation Rules) does not sufficiently validate input processed by rule definition functionality that utilizes a domain-specific scripting language. An authenticated attacker with specific business privileges could submit specially crafted input, which is interpreted as executable ABAP code by the rule processing logic. Successful exploitation could allow the attacker to execute ABAP arbitrary code into the system, resulting in full compromise of the affected system and high impact on confidentiality, integrity, and availability of the system.
