CVE-2026-42031Public exploitNetwork attack vector

Unauthenticated data disclosure via SQL injection

Published May 13, 2026 · Updated May 13, 2026

SQL injection in CKAN before 2.10.10 and 2.11.0 through 2.11.4 allows remote attackers to read private DataStore data. The datastore_search_sql query parser permits a crafted nested PostgreSQL function expression to access data outside authorized resources. The endpoint is unauthenticated but disabled by default; exposure requires DataStore SQL search to be enabled, and access includes PostgreSQL system information.
