Official 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.

Risk Analysis

Ruflo, an agent meta-harness, prior to version 3.16.3, exposed its MCP bridge POST /mcp and POST /mcp/:group endpoints without authentication in its default docker-compose deployment. This critical vulnerability allows unauthenticated network attackers to invoke terminal_execute, obtain a shell in the bridge container, read provider API keys, and poison AgentDB learning-store patterns. This vulnerability has a CVSSv3.1 score of 10.0, indicating maximum severity.

No public exploit is currently known for this vulnerability. The flaw is remotely exploitable without authentication, making it a high-risk target if an exploit emerges.

Recommended Action

Upgrade Ruflo to version 3.16.3 or later to fix this authentication bypass. Ensure that all sensitive API endpoints are properly authenticated and authorized, and review network configurations to restrict access to internal services.

Technical Analysis

CVE-2026-59726 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 10.0.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
