Denial of Service in GitLab GraphQL JSON Validation
CVE-2025-11447 is a denial-of-service vulnerability in GitLab Community Edition (CE) and Enterprise Edition (EE) affecting all versions from 11.0 before 18.3.5, 18.4 before 18.4.3, and 18.5 before 18.5.1. The flaw is in the JSON validation logic used when processing incoming GraphQL requests. An unauthenticated remote attacker can send specially crafted JSON payloads to the GitLab GraphQL endpoint, causing the validation path to consume excessive CPU and memory. This uncontrolled resource consumption can render the GitLab instance unresponsive. The issue is described as stemming from insufficient resource allocation limits or throttling in the vulnerable processing path, and GitLab remediated it by introducing stricter JSON schema validation to reject malformed requests.
