RCE in SAP Netweaver Application Server Java
CVE-2026-27674
Due to a Code Injection vulnerability in SAP NetWeaver Application Server Java (Web Dynpro Java), an unauthenticated attacker could supply crafted input that is interpreted by the application and causes it to reference attacker-controlled content. If a victim accesses the affected functionality, that attacker-controlled content could be executed in the victim�s browser, potentially resulting in session compromise. This could allow the attacker to execute arbitrary client-side code, impacting the confidentiality and integrity of the application, with no impact to availability.
