CVE-2026-48528Network attack vectorHinoki check available

Unauthenticated database compromise via appended nodeId

Published Aug 14, 2026 · Updated Aug 14, 2026

SQL injection in Metacat 2.0.0 through 3.4.0 allows remote attackers to read, insert, alter, or delete PostgreSQL data. The /cn/v1/object and /cn/v2/object handlers append the nodeId parameter to an SQL query without sanitization or parameterization and mirror database errors into XML responses. Unauthenticated network access to an enabled Coordinating Node REST API is sufficient, and crafted PostgreSQL errors expose arbitrary query results.
