CVE-2026-59726: Ruvnet Ruflo

Critical severity, CVSS 10.0. EPSS: 3% chance of exploitation in the next 30 days.

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.

Affected products

• Ruvnet Ruflo: before 3.16.3 (fixed in 3.16.3)
