CVE-2026-44895: GitLab MCP Server HTTP transport exposes unauthenticated RPC endpoint

Prior to version 0.6.0, the GitLab MCP Server's HTTP/SSE transport shipped with no inbound authentication, a wildcard Access-Control-Allow-Origin header, and a default bind to 0.0.0.0, exposing a mutation-capable RPC endpoint backed by the operator's GitLab personal access token. The issue is fixed in 0.6.0.

Disclosed 26 May 2026 · Record updated 13 September 2026

Impact

Any cross-origin browser context or network peer could reach the unauthenticated endpoint and perform GitLab operations using the operator's personal access token.
