CVE-2026-59726 is a critical-severity vulnerability rated 10/10 on the CVSS scale. 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. EPSS estimates a 0.44% chance of exploitation in the next 30 days.
