Private configuration disclosure via unauthenticated GraphQL requests

Published Mar 31, 2023 · Updated Feb 14, 2025

Improper access control in VTEX apps-graphql 2.x allows remote attackers to read private app configuration data through its GraphQL API. Version 2.x permits unauthenticated requests to obtain settings that its 3.x authorization policy restricts, including values such as API keys. Exploitation requires only network access to an affected store endpoint and exposes configuration secrets without allowing modification or service interruption.
