Executive Summary

This vulnerability in GitLab CE/EE versions before certain fixed releases allowed an unauthorized user to enumerate private projects. The issue was caused by incorrect authorization checks under certain conditions.

Impact Analysis

The impact of this vulnerability is that an unauthorized user could discover the existence of private projects that they should not have access to. This could lead to information disclosure about private projects, although it does not allow modification or deletion of data.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade GitLab CE/EE to a fixed version. Specifically, update to version 18.10.7 or later if you are using the 18.2 to 18.10 series, version 18.11.4 or later if you are using the 18.11 series, or version 19.0.1 or later if you are using the 19.0 series.
