The record
A stored cross-site scripting (XSS) vulnerability allows an attacker to execute arbitrary JavaScript in an administrator’s browser by registering a user whose **display name** contains HTML entities (e.g., `<img ...>`). When an administrator views the admin user list, the payload is decoded server-side and rendered without escaping, resulting in script execution in the admin context.
