Does this matter?
Lower severity and a low EPSS score (0.14%). Track it; it rarely justifies an emergency change on its own.
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.
