## Affected

- marmelab react-admin: fixed in 5.15.5

## Description

react-admin before 5.15.5 contains a stored cross-site scripting vulnerability that allows attackers to inject scripts by storing javascript: URIs in record fields rendered by UrlField and FileField. Attackers who can influence URL-type backend fields can execute JavaScript in an administrator's authenticated session when the administrator clicks the rendered link.
