CyberRota Analysis

AI-Generated

Deployments of the NL Portal Backend Libraries up to version 3.0.0 are vulnerable due to the exposure of unauthenticated GraphQL developer features, including the GraphiQL playground and schema introspection. This vulnerability allows attackers to easily map the API and potentially exploit other weaknesses, although it does not directly leak user data. Organizations using these libraries should prioritize upgrading to version 3.0.1 or implementing configuration changes to mitigate the risk.

Original NVD Description

NL Portal Backend Libraries provide backend components for Dutch government portals that interact with residents, customers, suppliers, and partner organizations. In versions up to and including 3.0.0, deployments using the shipped default configuration exposed two GraphQL developer features without requiring authentication: the GraphiQL playground, an interactive UI for issuing GraphQL queries; and schema introspection, which lets a caller download the full description of every query, mutation, type, and argument the API supports. Anyone who could reach the `/graphiql` endpoint could open the playground in a browser, pull the full schema, and use that to map out the API and craft calls against it. By itself this does not leak user data, but it removes the guesswork from attacking the rest of the API and significantly lowers the bar for finding and exploiting other weaknesses. Version 3.0.1 patches the issue. As a workaround, override the two settings in deployed configuration.
