What is CVE-2026-27682?

Due to a reflected cross-site scripting (XSS) vulnerability in SAP NetWeaver Application Server ABAP (Applications based on Business Server Pages), an unauthenticated attacker could craft a URL that exploits an unprotected URL parameter to embed a malicious script. If a victim clicks the link, the injected input is processed during web page generation, resulting in the execution of malicious content in the victim�s browser context. This could allow the attacker to access and/or modify information, impacting the confidentiality and integrity of the application, with no impact to availability.
