Apache Ranger versions before 0.6.3 could let an administrator save JavaScript inside custom policy conditions. That script could later run in a normal user’s browser when they log in and access policies. This is a stored cross-site scripting issue in a security administration interface.

The described actor must be an admin user, but impact can reach normal users who view affected policies. Treat this as a targeted cleanup item for legacy Apache Ranger. It is not documented as actively exploited here, but stored XSS in a security policy console can undermine trust in administrative workflows. Mitigation focus: Upgrade Apache Ranger to 0.6.3 or later where feasible.; Review Apache Ranger vendor vulnerability guidance for supported remediation details.; Restrict Apache Ranger admin access to trusted, monitored accounts..
