# CVE-2026-34260: SQL injection vulnerability in SAP S/4HANA (SAP Enterprise Search for ABAP)

- Severity: CVSS 9.6 (Critical), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-05-12 · Updated: 2026-05-12

## Affected

- SAP\_SE SAP S/4HANA (SAP Enterprise Search for ABAP): SAP\_BASIS 751, SAP\_BASIS 752, SAP\_BASIS 753, SAP\_BASIS 754, SAP\_BASIS 755, SAP\_BASIS 756, SAP\_BASIS 757, SAP\_BASIS 758, SAP\_BASIS 816

## Description

SAP S/4HANA (SAP Enterprise Search for ABAP) contains a SQL injection vulnerability that allows an authenticated attacker to inject malicious SQL statements through user-controlled input. The application directly concatenates this malicious user input into SQL queries, which are then passed to the underlying database without proper validation or sanitization. Upon successful exploitation, an attacker may gain unauthorized access to sensitive database information and could potentially crash the application. This vulnerability has a high impact on the confidentiality and availability of the application, while integrity remains unaffected.
