Impact Analysis

The impact of this vulnerability is the potential unauthorized disclosure of confidential information contained in issue titles within GitLab. An authenticated user could gain access to sensitive data that should remain private, which could lead to information leakage and compromise confidentiality.

Executive Summary

This vulnerability in GitLab CE/EE versions from 12.6 before 18.7.6, 18.8 before 18.8.6, and 18.9 before 18.9.2 allows an authenticated user to disclose confidential issue titles. The issue arises due to improper filtering under certain circumstances, which means that sensitive information in issue titles could be exposed to users who should not have access to it.
