Data schema exposed via GraphQL API public introspection

Moderate
mtrezza published GHSA-48q3-prgv-gm4w Jul 10, 2025

Package

npm parse-server (npm)

Affected versions

>= 5.3.0 <7.5.3, >=8.0.0 <8.2.2

Patched versions

>=7.5.3 <8.0.0, >=8.2.2

Description

Impact

The Parse Server GraphQL API previously allowed public access to the GraphQL schema without requiring a session token or the master key. While schema introspection reveals only metadata and not actual data, this metadata can still expand the potential attack surface.

Patches

The issue has been addressed by requiring the master key for schema introspection. Additionally, a new Parse Server configuration option, graphQLPublicIntrospection, has been introduced. This option allows developers to re-enable public schema introspection if their application relies on it. However, it is strongly recommended to use this option only temporarily and to update the application to function without depending on public introspection.

Workarounds

None available.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
