CVE-2026-82681— Query-parameter injection in AshAdmin row-action links via unencoded string primary keys

Quick assessment

Affected
ash-project ash_admin
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Ash Framework AshAdmin是Ash Framework组织的一款管理后台界面工具。 Ash Framework AshAdmin 0.3.0-rc.0版本至1.3.1之前版本存在输出处理不当漏洞，该漏洞源于输出编码或转义不当，通过原始字符串插值构造行操作URL而未进行URL编码，可能导致攻击者控制记录字符串主键注入参数，重写行操作链接目标，使管理员点击编辑时被发送到销毁表单或任意资源。

Vulnerability Title
Query-parameter injection in AshAdmin row-action links via unencoded string primary keys
Source: CVE Program / CVE List V5
Vulnerability 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.
