GraphQL Injection
Summary
GraphQL Injection allows an attacker to manipulate GraphQL queries to perform unauthorized operations, extract sensitive data, or execute arbitrary code.
Description
GraphQL Injection is a vulnerability that occurs when an attacker can manipulate GraphQL queries or their parameters to perform unauthorized operations, extract sensitive data, or execute arbitrary code on the server-side. Attackers can exploit this vulnerability by injecting malicious GraphQL queries or modifying existing queries to gain unauthorized access, escalate privileges, or compromise the integrity and confidentiality of the system.
Remediations
- Implement strict input validation and sanitization of user-controlled input used in GraphQL queries.
- Avoid building dynamic queries by concatenating user input. Instead, use query parameterization or prepared statements.
- Apply proper access controls and authorization mechanisms to restrict unauthorized access to sensitive data or operations.
- Regularly update and patch the GraphQL server implementation and dependencies.
