Descriptions

A vulnerability in GitLab CE/EE affecting all versions from 11.10 prior to 15.1.6, 15.2 to 15.2.4, 15.3 to 15.3.2 allows an authenticated user to achieve remote code execution via the Import from GitHub API endpoint.

Una vulnerabilidad en GitLab CE/EE afectando a todas las versiones desde la 11.10 anteriores a 15.1.6, desde la 15.2 hasta la 15.2.4, desde la 15.3 hasta la 15.3.2 permite a un usuario autenticado lograr la ejecución de código remota por medio del endpoint de la API Import from GitHub

An authenticated user can import a repository from GitHub into GitLab. If a user attempts to import a repo from an attacker-controlled server, the server will reply with a Redis serialization protocol object in the nested default_branch. GitLab will cache this object and then deserialize it when trying to load a user session, resulting in remote code execution.
