3 known CVE vulnerabilities in @zereight/mcp-gitlab, translated and rated.
- CVE-2026-61560Critical
`@zereight/mcp-gitlab` is a Model Context Protocol server for GitLab. Prior to version 2.1.27, the SSE transport mode (`SSE=true`) exposes all MCP tools without any authentication. The `upload_markdown` tool reads arbitrary files from the server's local filesystem via an unsanitized `file_path` parameter and uploads them to a GitLab project.
- CVE-2026-61568Critical
`@zereight/mcp-gitlab` is a Model Context Protocol server for GitLab. Versions prior to 2.1.30 expose the Streamable HTTP MCP endpoint without an effective Host or Origin allowlist. A malicious web page can use DNS rebinding to route browser requests to a victim's local MCP listener while preserving an attacker-controlled `Host` and `Origin`.
- CVE-2026-61559Critical
The @zereight/mcp-gitlab MCP server, in versions from 0.0.1 to 2.1.26 with ENABLE_DYNAMIC_API_URL=true, reads the X-GitLab-API-URL HTTP header and uses it as the base URL for outbound GitLab API calls. The server only validates URL format without any allowlist or hostname restriction, then attaches the victim's Private-Token to every redirected request. Version 2.1.27 contains a patch.
