CVE-2026-44759 SAP_SE CVE debrief

Who should care

Security teams responsible for SAP NetWeaver Enterprise Portal should assess and prioritize patching to prevent potential session information theft or content manipulation. IT operations teams should review and update their incident response plans to include procedures for detecting and responding to XSS attacks. Additionally, security teams should educate users on safe browsing practices and URL validation.

Technical summary

SAP NetWeaver Enterprise Portal is vulnerable to reflected cross-site scripting (XSS) attacks. An unauthenticated attacker can inject malicious scripts into a URL parameter, which are then reflected in the server response and executed in a user's browser when the crafted URL is visited. This could lead to theft of session information, manipulation of portal content, or user redirection. The attack has a low impact on the application's confidentiality and integrity, with no impact on availability. SAP has released notes and security patch day information related to this issue.

Defensive priority

Medium priority due to the potential for session information theft and content manipulation, with a CVSS score of 6.1.
