Executive Summary

This vulnerability affects GitLab Community Edition and Enterprise Edition versions from 10.8 before 18.6.6, 18.7 before 18.7.4, and 18.8 before 18.8.4. Under certain conditions, it allows an unauthenticated user to cause a denial of service by sending repeated GraphQL queries.

Impact Analysis

The vulnerability can lead to a denial of service (DoS) condition, meaning that an attacker who is not authenticated can repeatedly send GraphQL queries to the affected GitLab instance, potentially making the service unavailable to legitimate users.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade GitLab CE/EE to a fixed version. Specifically, update to version 18.6.6 or later if you are using the 18.6 branch, 18.7.4 or later for the 18.7 branch, or 18.8.4 or later for the 18.8 branch.

Avoid allowing unauthenticated users to send repeated GraphQL queries until the update is applied.
