Ash resources routinely use user-settable string primary keys (slugs, emails). Because Plug.Conn.Query resolves duplicate parameters last-wins and primary\\_key is interpolated last, a stored key such as foo&action\\_type=destroy injects parameters that override the link, so an admin clicking edit is sent to a destroy form or an arbitrary resource; a # truncates the query into a fragment. The fix builds every link with URI.encode\\_query/1, encoding all interpolated values.\n\nThis issue affects ash\\_admin: from 0.3.0-rc.0 before 1.3.1.","id":"EEF-CVE-2026-82681","modified":"2026-08-31T02:26:05.706351Z","published":"2026-08-31T02:26:05.357Z","references":[{"type":"ADVISORY","url":"https://github.com/ash-project/ash_admin/security/advisories/GHSA-j89q-xjrh-c26p"},{"type":"WEB","url":"https://cna.erlef.org/cves/CVE-2026-82681.html"},{"type":"FIX","url":"https://github.com/ash-project/ash_admin/commit/8e8ef91e8ba07498053887c6212f8b0f08178df6"},{"type":"PACKAGE","url":"https://hex.pm/packages/ash_admin"}],"related":[],"schema_version":"1.7.3","severity":[{"score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","type":"CVSS_V4"}],"summary":"Query-parameter injection in AshAdmin row-action links via unencoded string primary keys","upstream":[]}
