# CVE-2026-89122

> 6.1 MEDIUM

## Beschreibung

SAP NetWeaver Enterprise Portal does not sufficiently validate input to a certain portal component. An unauthenticated attacker could craft a malicious link that, when clicked by a victim, loads attacker-controlled content within the trusted application context. Successful exploitation could allow the attacker to track user information and deface parts of the rendered page, resulting in a low impact on confidentiality and integrity with no impact on availability.
