CVE-2026-44895 (opens in a new tab)How to fix?
Upgrade @yoda.digital/gitlab-mcp-server to version 0.6.0 or higher.
Overview
@yoda.digital/gitlab-mcp-server is a GitLab MCP Server - A Model Context Protocol server for GitLab integration
Affected versions of this package are vulnerable to Permissive Cross-domain Policy with Untrusted Domains via the SSE HTTP transport when USE_SSE=true is set, which lacks authentication and uses a wildcard CORS policy. An attacker can gain unauthorized access to all available GitLab tools and perform destructive operations by sending unauthenticated requests to the exposed endpoints from any network location or cross-origin browser context. This is only exploitable if the server is running with USE_SSE=true and is accessible from the attacker's network or browser context.
