Attack-Flow Graph

Executive Summary

This vulnerability in GitLab CE/EE versions before certain fixed releases allows an authenticated user to cause a denial of service (DoS). It occurs because the GraphQL API does not have sufficient resource allocation limits, which can lead to overwhelming system resources under certain conditions.

Impact Analysis

The impact of this vulnerability is a denial of service, meaning that an attacker who is authenticated could exhaust system resources and disrupt the availability of the GitLab service.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade GitLab CE/EE to a fixed version. Specifically, update to version 18.9.6 or later if you are using the 18.9 series, 18.10.4 or later for the 18.10 series, or 18.11.1 or later for the 18.11 series. These versions include the remediation for the denial of service caused by insufficient resource allocation limits in the GraphQL API.
