CVE-2026-44747
CWE-787Published: July 14, 2026· Updated: Jul 15, 2026
Official Description
SAP NetWeaver Application Server ABAP allows an authenticated attacker to leverage logical errors in memory management to cause a memory corruption that could lead to unauthorized data access, modification, or system unavailability. This has high impact on confidentiality, integrity, and availability of the application.
Risk Analysis
This critical vulnerability in SAP NetWeaver Application Server ABAP allows an authenticated attacker to cause memory corruption, leading to unauthorized data access, modification, or system unavailability. With a CVSS score of 9.9, this flaw poses a severe risk to the confidentiality, integrity, and availability of the application. There is no EPSS score to indicate exploitation likelihood, and it is not listed in CISA's KEV catalog.
No public exploit is known for this vulnerability. While it requires authentication, it is remotely exploitable with low attack complexity, meaning an attacker can exploit it over a network with valid credentials.
Apply the latest security patches from SAP for NetWeaver Application Server ABAP to address the logical errors in memory management. Implement strong authentication and authorization controls to limit access to the system.
Technical Analysis
CVE-2026-44747 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.9.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
From a weakness classification perspective (CWE-787): Out-of-bounds write vulnerabilities can lead to data corruption, crashes, or arbitrary code execution.
