CVE-2026-78693— Incomplete redaction re-attaches the original error path in AshGraphql, leaking internal field names

Quick assessment

Affected
ash-project ash_graphql
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.

以下是该漏洞描述的中文翻译： 在 ash-project 的 ash_graphql 中，存在一个“生成包含敏感信息的错误消息”漏洞。 远程客户端能够读取应用程序配置 本应屏蔽（redact）的内部字段名。 具体机制： 在 模块中，每个错误都会传递到已配置的 ，而返回的映射（map）会通过 与处理前的路径合并。 由于 仅在 handler 自身设置了 时才允许覆盖，若某个用于净化（sanitizing）的 handler 返回了一个全新的映射或删除了 键，这一决定会被撤销——因为合并操作会重新注入 。 该被重新注入

Vulnerability Title
Incomplete redaction re-attaches the original error path in AshGraphql, leaking internal field names
Source: CVE Program / CVE List V5
Vulnerability Description
Generation of Error Message Containing Sensitive Information vulnerability in ash-project ash_graphql allows a remote client to read internal field names that an application configured its error_handler to redact. In AshGraphql.Errors, each error is passed to the configured error_handler and the returned map is merged with the pre-handler path via Map.put_new(handled, :path, path). Because put_new defers to the handler only when the handler itself set :path, a sanitizing handler that returns a fresh map or deletes :path has that decision reverted. The re-injected path comes from build_error_path/5, which falls back to raw internal Ash attribute and argument names when no field_names mapping is configured. A validation failure on a non-exposed or nested field therefore returns internal names in the GraphQL error path, defeating the application's redaction. This issue affects ash_graphql: from 1.9.0 before 1.11.0.
