CVE-2026-49462Network attack vectorHinoki check available

Unauthenticated schema disclosure via enabled developer features

Published Sep 11, 2026 · Updated Sep 11, 2026

Information disclosure in NL Portal Backend before 3.0.1 allows remote attackers to enumerate its GraphQL API without authentication. The shipped application configuration enables the /graphiql developer UI and GraphQL schema introspection, exposing every supported query, mutation, type, and argument. Exposure requires the shipped defaults and reveals API structure rather than user data by itself, reducing the effort needed to identify other attack paths.
