CVE-2026-77846— JSON path injection via unescaped get_path segments in AshSqlite

Quick assessment

Affected
ash-project ash_sqlite
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： 数据查询逻辑中特殊元素未正确中和（Neutralization）漏洞 的 库中存在一个数据查询逻辑中特殊元素未正确中和的漏洞。该漏洞允许攻击者通过控制 的某个路径段，从而访问到应用程序本未暴露的嵌套 JSON 结构，进而泄露其中嵌入的私有或敏感字段。 技术细节： 使用 来构建 SQLite 的 路径。因此，如果某个路径段包含 、 、 或 ，该段会被重新解释为 JSON 路径语法（例如， 会被视为向下遍历两级，而不是作为一个单一的关键字）。由于路径是作为参数绑定的，因此该问题局限于 JS

Vulnerability Title
JSON path injection via unescaped get_path segments in AshSqlite
Source: CVE Program / CVE List V5
Vulnerability Description
Improper Neutralization of Special Elements in Data Query Logic vulnerability in ash-project ash_sqlite allows an attacker who controls a get_path/2 segment to traverse into nested JSON the application never exposed, disclosing private or sensitive? embedded fields. AshSqlite.SqlImplementation builds the SQLite json_extract path with "$." <> Enum.join(right, "."), so a single segment containing ., [, ], or $ re-interprets the JSON path (for example "private.secret" descends two levels instead of naming one key). The path is bound as a parameter, so this is confined to the JSON-path grammar rather than SQL. Any endpoint that lets user input reach a get_path segment (a common pick-a-field pattern) can read nested values it never meant to expose. This issue affects ash_sqlite: from 0.1.2-rc.0 before 0.2.18.
