Ruflo: Unauthenticated RCE in MCP bridge default docker-compose deployment

State: Published
Severity: 10.0 Critical
Published: Jul 9, 2026
Updated: Jul 9, 2026
Reserved: Jul 6, 2026

Description

Ruflo is an agent meta-harness for Claude Code and Codex. Prior to 3.16.3, ruflo's default docker-compose deployment exposed the MCP bridge POST /mcp and POST /mcp/:group endpoints without authentication, allowing an unauthenticated network attacker to invoke tools/call to terminal_execute, obtain a shell in the bridge container, read provider API keys, and poison AgentDB learning-store patterns. This issue is fixed in version 3.16.3.
