Cross-Site Scripting (XSS) in SAP NetWeaver JAVA (CVE-2026-44746)
Summary
Cross-site scripting in SAP NetWeaver JAVA (CVE-2026-44746). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
Due to a reflected cross-site scripting (XSS) vulnerability in SAP NetWeaver JAVA (JDBC Test Servlet), an unauthenticated attacker could craft a URL that embeds a malicious script. If a victim clicks this link, the injected input is processed during web page generation, resulting in the execution of malicious content in the victim's browser. This could allow the attacker to access and/or modify information related to the webclient, impacting the confidentiality and integrity of the application, with no impact to availability.
