Does this matter?

Lower severity and a low EPSS score (0.23%). Track it; it rarely justifies an emergency change on its own.

Description

A missing authorization vulnerability in Windmill Labs Windmill through 1.783.0 allows any authenticated workspace member to overwrite any resource type schema via the update_resource_type endpoint. The endpoint omits the administrator permission check that the corresponding delete_resource_type endpoint enforces. An attacker with workspace member privileges can corrupt resource type definitions, breaking workflows that depend on them.
