StorageGRID (formerly StorageGRID Webscale) versions prior to 11.8.0.15 and 11.9.0.8 are susceptible to a Reflected Cross-Site Scripting vulnerability. Successful exploit could allow an attacker to view or modify configuration settings or add or modify user accounts but requires the attacker to know specific information about the target instance and then trick a privileged user into clicking a specially crafted link.
