CVE-2026-0499Network attack vector

Script execution via unneutralized reflected URL parameter

Published Jan 13, 2026 · Updated Jan 13, 2026

Reflected XSS in SAP NetWeaver Enterprise Portal EP-RUNTIME 7.50 allows remote attackers to run scripts through a crafted URL. An unspecified portal handler copies a URL parameter into the server response without neutralizing script content; SAP has not named the parameter. No authentication is required, but a user must visit the crafted URL; the script runs in that user's browser and can steal session data, alter displayed portal content, or redirect the user.
