Summary

react-admin before 5.15.5 contains a cross-site scripting flaw in which record fields rendered by UrlField and FileField are not sanitized, so stored javascript: URIs are executed. An attacker with low privileges who can influence URL-type backend fields can run JavaScript in an administrator's authenticated session when the administrator clicks the rendered link, and user interaction is required.
