What is CVE-2026-81094 and which software is affected?

CVE-2026-81094 is a missing-authentication vulnerability (CWE-306) in mcp-router, an open-source MCP aggregator/CLI. All versions prior to 0.6.3 are affected. The vulnerability allows unauthenticated network access to the aggregator if authentication is not explicitly configured, exposing aggregated tool data and configuration to remote attackers.
Source: GitHub Security Advisory

How severe is CVE-2026-81094?

CVE-2026-81094 is rated Critical, with a CVSS v3.1 base score of 9.1 and a CVSS v4.0 score of 9.3. The vulnerability is network-exploitable, requires no authentication, and has a high confidentiality impact.
Source: CVE Project

What is the recommended mitigation for CVE-2026-81094?

Upgrade mcp-router to version 0.6.3 or later. This version changes the default bind address to localhost (127.0.0.1) and enforces authentication when a non-loopback host is specified. If immediate patching is not possible, restrict network access to the listening port, avoid binding to public interfaces without authentication, and audit deployments for exposure.
Source: Fix commit

How can I check if my organization is exposed to CVE-2026-81094?

Audit all mcp-router deployments for instances running versions prior to 0.6.3, especially those bound to 0.0.0.0 or other non-loopback interfaces without authentication. Review logs and network traffic for unexpected inbound connections to the mcp-router port. IONIX offers a free exposure report that maps all assets with this technology, identifies potentially exposed assets, and confirms verified exploitable assets. Request a scan.

IONIX Detection, Validation & Mitigation Workflow

How does IONIX detect and validate exposures to zero-day vulnerabilities like CVE-2026-81094?

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, and metadata inspection, to map every internet-facing asset. It continuously monitors dozens of threat intelligence feeds and applies AI to evaluate exploitability before public proof-of-concept code is available. IONIX filters vulnerabilities by attacker-centric criteria, validates exploitability with safe, non-intrusive payloads, and routes results through integrations with ticketing, SOAR, and SIEM tools for prioritized remediation.

New CVE Detected

CVE-2026-81094 – Missing Authentication / Unauthenticated Network Exposure – mcp-router before 0.6.3

Be the first to know when new zero-days emerge:

Summary

CVE-2026-81094 is a missing-authentication vulnerability (CWE-306) affecting mcp-router, an open-source MCP (Model Context Protocol) aggregator/CLI. In vulnerable versions, the serve command bound the aggregator to all network interfaces by default and only enforced authentication when an operator explicitly configured it, leaving the service reachable and usable by anyone who could route traffic to the listening port. The issue carries a CVSS v3.1 base score of 9.1 (CVSS v4.0: 9.3), reflecting network-exploitable, low-complexity, unauthenticated access with a high confidentiality impact.

Technical details

  • Root cause: The mcp-router serve command defaulted to binding on all network interfaces (0.0.0.0) rather than localhost, and did not mandate an authentication token unless the operator explicitly configured one.
  • Trigger conditions: Any deployment running mcp-router serve with default settings on a host reachable over a network (e.g., not restricted by firewall/NAT) is exposed; no special configuration is required to trigger exposure — it is the out-of-the-box behavior.
  • Attack vector: Network (AV:N) — a remote, unauthenticated attacker who can reach the exposed port can connect directly to the MCP aggregator.
  • Impact: Unauthorized access to the MCP aggregator allows an attacker to interact with aggregated MCP servers/tools without credentials, resulting in high confidentiality impact (potential exposure of aggregated tool data/configuration); integrity/availability impact is not indicated in the scoring (I:N/A:N per CVSS v3.1 vector observed in source data, C:H).

Affected software

  • Product: mcp-router (https://github.com/mcp-router/mcp-router)
  • Versions affected: All versions prior to 0.6.3
  • Fixed version: 0.6.3 and later (fix commit 4c4642cfd274097ec8b33ecd3047390829c79d35)

Severity

  • CVSS v3.1 Base Score: 9.1 (Critical) — CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
  • CVSS v4.0 Score: 9.3 (Critical) — CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N
  • CWE-306: Missing Authentication for Critical Function

Mitigation and recommended actions

  • Immediate: Upgrade mcp-router to version 0.6.3 or later, which changes the serve command’s default bind address to 127.0.0.1 (localhost only) and enforces that a --token be supplied whenever a non-loopback --host is specified, ensuring network-exposed instances require authentication.
  • If immediate patching is not possible:
    • Restrict network access to the mcp-router listening port using host-based firewalls, security groups, or network segmentation so it is reachable only from trusted hosts.
    • Do not run serve bound to a public or non-loopback interface without explicitly configuring an authentication token.
    • Audit existing deployments for instances currently bound to 0.0.0.0 or other non-loopback interfaces without authentication configured, and reconfigure them to bind to localhost or require a token immediately.
    • Review logs/network traffic for unexpected inbound connections to the mcp-router port as an indicator of possible exploitation prior to remediation.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
