A batch loader function in Spring for GraphQL versions 1.1.0 - 1.1.5 and 1.2.0 - 1.2.2 may be exposed to GraphQL context with values, including security context values, from a different session. An application is vulnerable if it provides a DataLoaderOptions instance when registering batch loader functions through DefaultBatchLoaderRegistry.

Versions of the package graphql from 16.3.0 and before 16.8.1 are vulnerable to Denial of Service (DoS) due to insufficient checks in the OverlappingFieldsCanBeMergedRule.ts file when parsing large queries. This vulnerability allows an attacker to degrade system performance. **Note:** It was not proven that this vulnerability can crash the process.

The VTEX apps-graphql@2.x GraphQL API module does not properly restrict unauthorized access to private configuration data. (apps-graphql@3.x is unaffected by this issue.)

In GraphQL Java (aka graphql-java) before 20.1, an attacker can send a crafted GraphQL query that causes stack consumption. The fixed versions are 20.1, 19.4, 18.4, 17.5, and 0.0.0-2023-03-20T01-49-44-80e3135.

`silverstripe/graphql` serves Silverstripe data as GraphQL representations. In versions 4.2.2 and 4.1.1, an attacker could use a specially crafted graphql query to execute a denial of service attack against a website which has a publicly exposed graphql endpoint. This mostly affects websites with particularly large/complex graphql schemas. Users should upgrade to `silverstripe/graphql` 4.2.3 or 4.1.2 to remedy the vulnerability.

Hasura is an open-source product that provides users GraphQL or REST APIs. A path traversal vulnerability has been discovered within Hasura GraphQL Engine prior to versions 1.3.4, 2.55.1, 2.20.1, and 2.21.0-beta1. Projects running on Hasura Cloud were not vulnerable. Self-hosted Hasura Projects with deployments that are publicly exposed and not protected by a WAF or other HTTP protection layer should be upgraded to version 1.3.4, 2.55.1, 2.20.1, or 2.21.0-beta1 to receive a patch.

Hasura GraphQL Engine before 2.15.2 mishandles row-level authorization in the Update Many API for Postgres backends. The fixed versions are 2.10.2, 2.11.3, 2.12.1, 2.13.2, 2.14.1, and 2.15.2. (Versions before 2.10.0 are unaffected.)

ezplatform-graphql is a GraphQL server implementation for Ibexa DXP and Ibexa Open Source. Versions prior to 2.3.12 and 1.0.13 are subject to Insecure Storage of Sensitive Information. Unauthenticated GraphQL queries for user accounts can expose password hashes of users that have created or modified content, typically administrators and editors. This issue has been patched in versions 2.3.12, and 1.0.13 on the 1.X branch. Users unable to upgrade can remove the "passwordHash" entry from "src/bundle/Resources/config/graphql/User.types.yaml" in the GraphQL package, and other properties like hash type, email, login if you prefer.

graphql-java before19.0 is vulnerable to Denial of Service. An attacker can send a malicious GraphQL query that consumes CPU resources. The fixed versions are 19.0 and later, 18.3, and 17.4, and 0.0.0-2022-07-26T05-45-04-226aabd9.

graphql-go (aka GraphQL for Go) through 0.8.0 has infinite recursion in the type definition parser.
