CVE-2026-7428 PUBLISHED

Insecure default administrative credentials in AlloyDB for PostgreSQL

Assigner: GoogleCloud
Reserved: 29.04.2026 Published: 12.05.2026 Updated: 12.05.2026

Prior to 2025-11-03, well-intended users of Terraform or REST API for Google Cloud AlloyDB for PostgreSQL could have created clusters with an insecure default password which could have been exploited by a remote attacker to gain full administrative access to the database.

Exploitation required network access to the AlloyDB cluster and was limited to Terraform or the REST API, as other clients blocked it.
