CVE-2025-55282Network attack vector

PostgreSQL superuser escalation via unrestricted search_path

Published Aug 18, 2025 · Updated Aug 18, 2025

Privilege escalation in Aiven aiven-db-migrate before 1.0.7 allows remote authenticated users to gain PostgreSQL superuser access. During migration, the tool leaves search_path unrestricted, allowing source-controlled objects to override pg_catalog and run operators with target-side superuser privileges. Exploitation requires control of an untrusted source database and a migration account whose target connection has superuser or equivalent rights.
