CVE-2026-0499 - SAP NetWeaver Enterprise Portal Plugin
CVE-2026-0499
SAP NetWeaver Enterprise Portal allows an unauthenticated attacker to inject malicious scripts into a URL parameter. The scripts are reflected in the server response and executed in a user's browser when the crafted URL is visited, leading to theft of session information, manipulation of portal content, or user redirection, resulting in a low impact on the application's confidentiality and integrity, with no impact on availability.
