CVE-2026-62845: SQL Injection (CVSS 4.7)

Description

Kamaji is the Hosted Control Plane Manager for Kubernetes. Prior to 26.7.4-edge, the PostgreSQL and MySQL datastore drivers build DDL statements by interpolating the user-supplied DataStoreUsername/DataStoreSchema directly into SQL via fmt.Sprintf, without escaping identifiers. These fields have no format validation, so a value containing a quote character breaks out of the quoted identifier — SQL injection executed over Kamaji's root connection to the shared datastore. etcd driver is not affected.This issue is fixed in version 26.7.4-edge.
