Mitigation Strategies

To mitigate this vulnerability, you should upgrade GitLab CE/EE to a fixed version. Specifically, update to version 18.7.6 or later if you are using the 18.7 series, 18.8.6 or later for the 18.8 series, or 18.9.2 or later for the 18.9 series.

Executive Summary

This vulnerability in GitLab CE/EE versions before 18.7.6, 18.8.6, and 18.9.2 allows an authenticated user to make unintended internal requests through proxy environments. It occurs due to improper input validation in the import functionality, which could be exploited under certain conditions.

Impact Analysis

The vulnerability could allow an authenticated user to send unintended internal requests, potentially exposing internal services or data that should not be accessible. This could lead to partial confidentiality loss within the affected GitLab environment.
