Query-parameter injection in AshAdmin row-action links via unencoded string primary keys
Quick fix
EEF-CVE-2026-82681 — ash_admin: upgrade to the fixed version with the command below.
mix deps.update ash_adminDetails
## Summary
Improper Encoding or Escaping of Output vulnerability in ash-project ash\_admin lets an attacker who controls a record's string primary key rewrite the target of AshAdmin's row-action links.
The Table, DataTable, and Show components built row-action URLs by raw string interpolation, splicing the primary key (and table, domain, and resource names) into the query string without URL-encoding. 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.
This issue affects ash\_admin: from 0.3.0-rc.0 before 1.3.1.
