BIT-gitlab-2025-12506: Use of Incorrectly-Resolved Name or Reference in GitLab
A vulnerability in GitLab CE/EE versions from 16.5 before 18.11.7, 19.0 before 19.0.4, and 19.1 before 19.1.2 allows an authenticated user to create a repository where the content shown in the web interface differs from the content available for download. This is due to improper handling of Git reference name resolution.
AI Analysis
