About Sap Advanced Planning And Optimization
CVE-2026-23689 affects Sap Advanced Planning And Optimization, a product from Sap. Before acting, confirm where Sap Advanced Planning And Optimization runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.
What the flaw is
In plain terms: Due to an uncontrolled resource consumption (Denial of Service) vulnerability, an authenticated attacker with regular user privileges and network access can repeatedly invoke a remote-enabled function module with an excessively large loop-control parameter. This triggers prolonged loop execution that consumes excessive system resources, potentially rendering the system unavailable. Successful exploitation results in a denial-of-service condition that impacts availability, while confidentiality and integrity remain unaffected.
The weakness class is Allocation Without Limits. Resources are allocated without a cap.
Based on its CVSS vector, the flaw can be reached over the network, needs some level of access, and needs no user interaction. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.

How to detect it
- Inventory every instance of Sap Advanced Planning And Optimization and record the running version against the affected range above.
- Check external attack surface scans for internet facing instances of the component.
- Review logs on affected systems for unusual requests, errors or new processes around the vulnerable function.
- Confirm with an authenticated vulnerability scan once your scanner has a check for this CVE.
How to fix it
- Apply the fixed version of Sap Advanced Planning And Optimization named in the vendor advisory.
- If patching must wait, restrict network access to the affected service and put it behind authentication or a web application firewall rule.
- Rescan after the change to prove the exposure is gone, then close the ticket.

Related CVEs
The SAP BusinessObjects Business Intelligence Platform allows an authenticated attacker with high privileges to insert malicious URL within the application. Upon successful exploitation, the victim may click on this malicious URL, resulting in an unvalidated redirect to the attacker-controlled domain and subsequently download the malicious content. This vulnerability has a high impact on the confidentiality and integrity of the application, with no effect on the availability of the application.
An authenticated attacker in SAP CRM and SAP S/4HANA (Scripting Editor) could exploit a flaw in a generic function module call and execute unauthorized critical functionalities, which includes the ability to execute an arbitrary SQL statement. This leads to a full database compromise with high impact on confidentiality, integrity, and availability.
Due to the usage of vulnerable third party component in SAP Wily Introscope Enterprise Manager (WorkStation), an unauthenticated attacker could create a malicious JNLP (Java Network Launch Protocol) file accessible by a public facing URL. When a victim clicks on the URL the accessed Wily Introscope Server could execute OS commands on the victim's machine. This could completely compromising confidentiality, integrity and availability of the system.
SAP S/4HANA (Private Cloud and On-Premise) allows an attacker with admin privileges to exploit a vulnerability in the function module exposed via RFC. This flaw enables the injection of arbitrary ABAP code/OS commands into the system, bypassing essential authorization checks. This vulnerability effectively functions as a backdoor, creating the risk of full system compromise, undermining the confidentiality, integrity and availability of the system.
When processing HTTP/2 SETTINGS frames, transport will enter an infinite loop of writing CONTINUATION frames if it receives a SETTINGS_MAX_FRAME_SIZE with a value of 0.
