Lifecycle Timeline
4Description
@delmaredigital/payload-puck is a PayloadCMS plugin for integrating Puck visual page builder. Prior to 0.6.23, all /api/puck/* CRUD endpoint handlers registered by createPuckPlugin() called Payload's local API with the default overrideAccess: true, bypassing all collection-level access control. The access option passed to createPuckPlugin() and any access rules defined on Puck-registered collections were silently ignored on these endpoints. This vulnerability is fixed in 0.6.23.

The vulnerability stems from hardcoded overrideAccess: true in API endpoint handlers, completely circumventing collection-level access controls that developers implemented. …
