🎯 GitLab CE/EE Path Traversal Vulnerability (CVE-2023-2825)

On May 23, 2023, GitLab released version 16.0.1, which addressed a critical vulnerability, CVE-2023-2825, impacting both the Community Edition (CE) and Enterprise Edition (EE) version 16.0.0. This vulnerability enables unauthenticated users to read arbitrary files by exploiting a path traversal bug. Additionally, an unauthenticated malicious user can leverage a path traversal vulnerability to read arbitrary files on the server if there is an attachment present in a public project nested within a minimum of five groups.
