Detailsinfo

A vulnerability was found in parse-community parse-server up to 9.5.0-alpha.9. It has been classified as problematic. Affected is an unknown function of the component graphQLPublictrospection. The manipulation with an unknown input leads to a authorization vulnerability. CWE is classifying the issue as CWE-863. The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions. This is going to have an impact on confidentiality. CVE summarizes:

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. From version 9.3.1-alpha.3 to before version 9.5.0-alpha.10, when graphQLPublicIntrospection is disabled, __type queries nested inside inline fragments (e.g. ... on Query { __type(name:"User") { name } }) bypass the introspection control, allowing unauthenticated users to perform type reconnaissance. __schema introspection is not affected. This issue has been patched in version 9.5.0-alpha.10.
