CVE-2026-27674Network attack vector

Session compromise via attacker-controlled content execution

Published Apr 14, 2026 · Updated Apr 14, 2026

Code injection in SAP NetWeaver Application Server Java WD-RUNTIME 7.50 allows remote attackers to run code in a victim's browser. Web Dynpro Java interprets crafted unauthenticated input as a reference to attacker-controlled content, which the browser executes when the affected functionality is opened. Exploitation requires a victim to access that functionality and permits session compromise with client-side confidentiality and integrity impact, but no service interruption.
