Related CVEs

  1. SAP Commerce Cloud could retain a sample OAuth2 client with publicly documented sample credentials originating from sample configuration provided in SAP Help Portal documentation. If left unchanged, an unauthenticated attacker could use these well-known credentials to obtain a valid access token and invoke certain APIs to read and modify data. Successful exploitation results in high impact on confidentiality and integrity, with no impact on availability.•CVE-2026-44761
  2. Due to an HTTP Request Smuggling vulnerability in SAP Approuter, an unauthenticated attacker could send a specially crafted HTTP request that leads to request-response desynchronization. This could result in the exposure of user responses and cause the system to become unavailable. This leads to a high impact on confidentiality and availability.•CVE-2026-27690
  3. Due to improper RFC protocol validation in the SAP Kernel used by the Application Server ABAP of SAP NetWeaver and ABAP Platform, an unauthenticated attacker can send a crafted RFC request that exploits logical errors in memory management, leading to memory corruption. This could lead to a high impact on the confidentiality, integrity, and availability of the application.•CVE-2026-27671
  4. 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.•CVE-2026-34259
  5. 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.•CVE-2026-34260
