AI-suggested
Upgrade to version 2.1.27 or later, which contains a patch that restricts access and sanitizes the `file_path` parameter. Until upgraded, avoid enabling SSE transport mode (`SSE=true`) in untrusted environments or restrict network access to trusted users only.
Description
`@zereight/mcp-gitlab` versions prior to 2.1.27 have a critical path traversal vulnerability in the SSE transport mode that allows unauthenticated attackers to read arbitrary files on the server. This can lead to theft of sensitive tokens and full GitLab account takeover. Version 2.1.27 includes a patch for this issue.
