Rapyd Admin from 9.4.0 before 9.20.0 contains a stored cross-site scripting vulnerability that allows unauthenticated attackers to inject scripts through self-registered display names. Attackers can register with an HTML or JavaScript name rendered unescaped in the Activity log Author filter, executing in an administrator's session.
