CVE-2026-24312 is a vulnerability identified in SAP Business Workflow, specifically within the SAP_BASIS component versions 7.52 through 8.16. The root cause is a missing authorization check (CWE-862) that allows an authenticated administrative user to bypass role restrictions. This bypass occurs because the system erroneously allows permissions granted for less sensitive functions to be leveraged to perform unauthorized, high-privilege actions. The vulnerability does not affect confidentiality significantly and has no impact on availability, but it has a high impact on data integrity, as unauthorized changes to workflows or business processes can occur. The CVSS 3.1 base score is 5.2 (medium severity), reflecting that exploitation requires network access, low attack complexity, high privileges, and user interaction. The scope remains unchanged, meaning the vulnerability affects only the component where it exists. No public exploits are known at this time, but the flaw could be exploited by insiders or attackers who have gained administrative access to escalate privileges further and manipulate critical business workflows. The vulnerability highlights the importance of robust authorization checks in complex enterprise applications like SAP to prevent privilege escalation and unauthorized actions within business-critical processes.

For European organizations, this vulnerability poses a significant risk to the integrity of business workflows managed through SAP Business Workflow. Unauthorized privilege escalation can lead to manipulation or corruption of critical business processes, potentially resulting in financial discrepancies, compliance violations, and operational disruptions. Although confidentiality and availability impacts are low, the integrity compromise can undermine trust in business data and processes, which is critical for sectors such as finance, manufacturing, and public administration. Given SAP's widespread use across Europe, especially in large enterprises and government entities, exploitation could facilitate fraud, unauthorized transactions, or sabotage of automated workflows. The requirement for authenticated administrative access limits external threat actors but raises concerns about insider threats or compromised administrative accounts. Organizations may also face regulatory scrutiny under GDPR if workflow manipulations lead to improper handling of personal data or reporting inaccuracies.

1. Apply SAP vendor patches promptly once they are released for the affected SAP_BASIS versions to address the missing authorization check. 2. Conduct a thorough review and tightening of role-based access controls (RBAC) within SAP Business Workflow to ensure that permissions are strictly segregated and least privilege principles are enforced. 3. Implement enhanced monitoring and logging of administrative actions within SAP workflows to detect unusual privilege escalations or unauthorized activity early. 4. Enforce multi-factor authentication (MFA) for all administrative accounts to reduce the risk of credential compromise. 5. Regularly audit SAP user roles and permissions to identify and remediate any excessive or unnecessary privileges. 6. Train SAP administrators and security teams on the risks of privilege escalation and the importance of strict authorization checks. 7. Consider network segmentation and limiting administrative access to SAP systems to trusted internal networks only. 8. Prepare incident response plans specific to SAP workflow integrity breaches to enable rapid containment and recovery.
