CVE-2026-35441— Directus Affected by GraphQL Alias Amplification Denial-of-Service Due to Missing Query Cost/Complexity Limits

Directus Affected by GraphQL Alias Amplification Denial-of-Service Due to Missing Query Cost/Complexity Limits

Directus is a real-time API and App dashboard for managing SQL database content. Prior to 11.17.0, Directus' GraphQL endpoints (/graphql and /graphql/system) did not deduplicate resolver invocations within a single request. An authenticated user could exploit GraphQL aliasing to repeat an expensive relational query many times in a single request, forcing the server to execute a large number of independent complex database queries concurrently, multiplying database load linearly with the number of aliases. The existing token limit on GraphQL queries still permitted enough aliases for significant resource exhaustion, while the relational depth limit applied per alias without reducing the total number executed. Rate limiting is disabled by default, meaning no built-in throttle prevented this from causing CPU, memory, and I/O exhaustion that could degrade or crash the service. Any authenticated user, including those with minimal read-only permissions, could trigger this condition. This vulnerability is fixed in 11.17.0.

未加控制的资源消耗(资源穷尽)

Directus 安全漏洞

Directus是Directus开源的一个实时 Api 和应用程序仪表板。用于管理 Sql 数据库内容。 Directus 11.17.0之前版本存在安全漏洞，该漏洞源于GraphQL端点未在单个请求中重复数据删除解析器调用，可能导致资源耗尽。
