CVE-2026-89107

SAP S/4HANA does not perform sufficient instance-level authorization checks for certain modification operations on associated business object data. An attacker with low privileges and local access to the system could bypass authorization checks to modify data belonging to objects they are not authorized for.

Vulnerability in SAP S/4HANA (Private Cloud and On-Premise) allows an attacker with admin privileges to inject arbitrary ABAP code or OS commands via the RFC-exposed function module, bypassing authorization checks.

SAP S/4HANA (Manage Bank Chains app) does not perform sufficient authorization checks within certain functionality. A low-privileged attacker could send specially crafted requests to delete entries that should not be accessible. This results in a low impact on availability, with no impact on confidentiality and integrity.

SAP S/4HANA (Intercompany Matching and Reconciliation) allows a low-privileged authenticated user to inject malicious input into certain functions, which may be processed by the database without proper validation. This could allow access to sensitive information, resulting in high impact on confidentiality, with no impact on integrity and availability.

SAP S/4HANA (Private Cloud) uses a third-party component that contains a Regular Expression Denial of Service (ReDoS) vulnerability. An unauthenticated attacker could supply specially crafted input that triggers excessive processing within the affected functionality. Successful exploitation could exhaust system resources and make the service unavailable, resulting in a high impact on availability. There is no impact on confidentiality and integrity.

Reprocess Bank Statement Items in SAP S/4HANA does not perform the necessary authorization checks for authenticated users, allowing them to use rules that have not been shared with them, resulting in privilege escalation.

In SAP S/4HANA, the Draft operation does not perform necessary authorization checks for an authenticated user. A restricted user could access information within the entity, resulting in escalation of privileges.

A vulnerability in SAP S/4HANA Project Management (PPM-PRO) allows an attacker with high privileges to execute crafted database queries, exposing the backend database. This results in low impact on confidentiality, with no impact on integrity and availability.

SAP S/4HANA (On-Premise) has an SQL injection vulnerability in a remote-enabled function module. An authenticated attacker can execute unauthorized database queries, exposing sensitive information.

Vulnerability in SAP S/4HANA (Manage Processing Rules - For Bank Statements) allows an authenticated attacker with basic privileges to delete conditions from any shared rule of any user by tampering the request parameter. Due to missing authorization check, the attacker can delete shared rule conditions that should be restricted, compromising the integrity of the application without affecting its confidentiality or availability.
