What is CVE-2026-77846?
CVE-2026-77846 is a low-severity vulnerability in ash-project ash_sqlite, published on 30 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
Weakness: CWE-943
