8.2.2- Upgrade parse-server to this version or later
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.

How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-497: Exposure of Sensitive System Information to an Unauthorized Control Sphere
The product does not properly prevent sensitive system-level information from being accessed by unauthorized actors who do not have the same level of access to the underlying system as the product does.
How to prevent it
- Architecture and Design, Implementation: Production applications should never use methods that generate internal details such as stack traces and error messages unless that information is directly committed to a log that is not viewable by the end user. All error message text should be HTML entity encoded before being written to the log file to protect against potential cross-site scripting attacks against the viewer of the logs
