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.

Ash Framework AshSqlite是Ash Framework组织的一个Ash Framework的SQLite数据层。 Ash Framework AshSqlite 0.1.2-rc.0版本至0.2.18之前版本存在输入验证错误漏洞，该漏洞源于数据查询逻辑中的特殊元素中和不当，可能导致攻击者控制get_path/2段遍历应用程序未暴露的嵌套JSON，泄露私有或敏感字段。

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.
