CVE-2026-61560critical · fixedCVSS 9.8

@zereight/mcp-gitlab: Unauthenticated arbitrary file read via `upload_markdown` enables PAT exfiltration and full account takeover

### Summary 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. Combined, any unauthenticated network-reachable attacker can read `/proc/self/environ` to steal the server's `GITLAB_PERSONAL_ACCESS_TOKEN` and achieve full GitLab account takeover. This is the default configuration for Docker deployments

@zereight/mcp-gitlab: DNS rebinding reaches local Streamable HTTP MCP transport

`@zereight/mcp-gitlab` exposes its 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`. The server accepts those headers and reaches the MCP initialization path instead of rejecting the request at the HTTP boundary. This is CWE-350, Reliance on Reverse DNS Resolution for a Security-Critical Action. The affected

@zereight/mcp-gitlab has multiple safety-control bypasses: execute_graphql read-only + allow-list bypass, unauthenticated transports, session-exhaustion DoS

### Summary @zereight/mcp-gitlab exposes GitLab to an LLM agent while relying on read-only mode, a project allow-list, and transport auth as its safety controls. Five defects defeat those controls. Under the MCP threat model, tool-call arguments/content can be shaped by untrusted input (prompt injection) or a malicious client. Reviewed commit: 60adcc0de5b0e96c4c2029f7a25d2775946421d8 (package version 2.1.28). Source review only; PoCs are local/offline. - F1 (HIGH) execute_graphql defeats BOTH
