Ash resources routinely use user-settable string primary keys (slugs, emails). Because <code>Plug.Conn.Query</code> resolves duplicate parameters last-wins and <code>primary_key</code> is interpolated last, a stored key such as <code>foo&amp;action_type=destroy</code> injects parameters that override the link, so an admin clicking <code>edit</code> is sent to a destroy form or an arbitrary resource; a <code>#</code> truncates the query into a fragment. The fix builds every link with <code>URI.encode_query/1</code>, encoding all interpolated values.</p>\n<p>This issue affects ash_admin: from 0.3.0-rc.0 before 1.3.1.</p>"
