Summary
Stored Cross-site Scripting vulnerability in ash-project ash_admin executes attacker-supplied record content as script in an administrator's browser.
The relationship typeahead components
AshAdmin.Components.Resource.RelationshipFieldandAshAdmin.Components.Resource.ManagedRelationshipSelectFieldhighlight the matched search term by wrapping it in<b>tags and rendering the whole string withPhoenix.HTML.raw/1. The highlighted value is the destination record'slabel_field, ordinary database content that is often written by lower-privileged users. Becauseraw/1disables output escaping for the entire string, a stored label such as<img src=x onerror=...>runs as JavaScript in the admin's session as soon as a matching record appears in the dropdown, giving the attacker the admin's privileges over everything AshAdmin exposes. The fix HTML-escapes the label before inserting the highlight markup.This issue affects ash_admin: from 0.13.0 before 1.3.1.
