CVE-2026-82681
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.
Does this matter?
Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.
Description
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.
