GraphQL, a flexible and efficient query language for APIs, is seeing rapid adoption across enterprises. A recent report titled “The State of GraphQL Security 2024” reveals critical insights into the security landscape of GraphQL APIs.
Based on the analysis of 13,000 GraphQL API issues, underscores the urgent need for improved security measures as the technology becomes more prevalent.
Key Findings
According to Gartner, the adoption of GraphQL is set to increase significantly, with projections indicating that by 2027, over 60% of enterprises will use GraphQL in production, up from less than 30% in 2024. This rapid growth highlights the necessity of addressing security vulnerabilities inherent in GraphQL APIs.
The Escape report shared with Cyber Security News identified a total of 13,720 issues across various GraphQL services, with 4,527 classified as highly critical. On average, each GraphQL service had 87 issues, a significant increase from the previous year due to enhanced scanning tools and more in-depth coverage. The severity breakdown is as follows:
- High Severity: 33% of API services had at least one high-severity issue.
- Medium Severity: 72% of services were vulnerable to medium-level issues.
- Low Severity: 78% had low-severity issues.
Main Attack Vectors
The primary vulnerabilities identified include:
- Unrestricted Resource Consumption: Nearly 69% of API services were susceptible to Denial of Service (DoS) attacks due to lack of proper rate limiting and resource allocation mechanisms.
- Security Misconfiguration: Approximately 11.1% of services had issues related to improper customization and configuration, leading to security gaps.
- Exposed Secrets: Over 4,000 exposed secrets, including access tokens, passwords, and credit card numbers, were found in GraphQL API responses.
The report also highlights industry-specific vulnerabilities, with the financial services and technology sectors being the most affected. Financial institutions, in particular, face significant risks due to the sensitive nature of the data they handle.
Despite the critical role of APIs in enhancing agility and innovation, many financial institutions still lack proactive security measures, leaving them vulnerable to breaches.
The report emphasizes the importance of compliance with security standards such as GDPR, PCI DSS, and ISO 27001. Almost all tested APIs were non-compliant with at least one type of compliance standard. The most common compliance issue was related to broken authentication and session management, accounting for 59.8% of PCI DSS compliance issues.

Recommendations for Improved Security
To address these vulnerabilities, the report recommends several best practices:
- Access Control with Authorization and Authentication: Implementing robust authorization and authentication mechanisms to prevent unauthorized access.
- Input Validation: Ensuring all incoming requests are validated to protect against injection attacks.
- Rate Limiting: Setting limits on queries and mutations to block brute-force attacks.
- Depth Limiting: Using tools like graphql-armor to limit the depth of queries and prevent DoS attacks.
- Schema Whitelisting: Limiting the exposed schema to necessary types and fields to reduce the attack surface.
- Cost Limiting: Implementing hard limits on query costs to manage resource consumption effectively.
The “State of GraphQL Security 2024” report highlights the critical need for enhanced security measures as GraphQL adoption continues to rise. By implementing best practices and proactive security strategies, organizations can protect their GraphQL APIs from potential vulnerabilities and ensure the integrity and confidentiality of their data.
