CVE-2026-42032Network attack vector

Unauthenticated data disclosure via incomplete table authorization

Published May 13, 2026 · Updated May 13, 2026

Incorrect authorization in CKAN before 2.10.10 and 2.11.0 through 2.11.4 allows remote attackers to read private DataStore resources. The datastore_search_sql action resolves tables from an attacker-supplied SQL query but fails to enforce access rights for every resolved resource, exposing private tables and PostgreSQL system information. The API endpoint is reachable without authentication only when ckan.datastore.sqlsearch.enabled is enabled; this setting is disabled by default.
