Technical details
The vulnerability is an authorization bypass (CWE-862) in the ALTER TYPE statement parser. The edge-type setters setLightweight() and setUnique() in LocalEdgeType lack the checkForSchemaMutation() call that enforces UPDATE_SCHEMA permission. When ALTER TYPE is issued with only a WITH clause (no ALTER items), the per-item authorization loop is skipped and the unguarded setters are called directly, allowing a read-only authenticated user to persist schema changes. An attacker needs only a valid read-only database credential and network access to the HTTP, gRPC, or Bolt command API (enabled by default).
