CVE-2025-53364 Scanner

Parse Server is an open-source platform that provides backend support for mobile applications. Developed by the Parse Community, it facilitates the management of applications requiring data storage and synchronization. The software serves developers who need to implement performant and scalable backend services without deep server-side development expertise. It is widely adopted for building web and mobile applications, offering functionalities such as data storage, user authentication, and notifications. Its GraphQL API allows developers to interact with their data in a flexible manner, enhancing application development efficiency.

This vulnerability affects the security of Parse Server by disclosing GraphQL schema information without requiring authentication. It allows unauthorized users to access metadata about the schema, which could potentially reveal sensitive information. Schema introspection should be restricted to prevent exposing an application's internal structure, which could assist attackers in crafting specific attacks. Such vulnerabilities underscore the importance of proper authentication and authorization mechanisms in software dealing with sensitive data. Mitigating these vulnerabilities helps protect against unauthorized access and potential exploitation.

The vulnerability is in the GraphQL API endpoint of the Parse Server, where the schema introspection is publicly accessible. Attackers can send specific GraphQL queries that retrieve details about the available types and fields. The exposure is due to the GraphQL API not enforcing authentication requirements, such as a session token or master key. The vulnerability primarily leaks metadata and not directly sensitive application data. Nonetheless, the metadata can still assist attackers in understanding and exploiting the application further.

When exploited, this vulnerability may lead to enhanced attack vectors and the discovery of more vulnerabilities within the application. Information about the application's schema can facilitate targeted attacks, making it easier for attackers to execute more sophisticated payloads. Additionally, unintentional data exposure can occur if developers are unaware of the potential access granted through this vulnerability. It is essential to harden the application's access controls to limit the attack surface.
