Frequently Asked Questions

About CVE-2026-11720

What is CVE-2026-11720 and which software is affected?

CVE-2026-11720 is a critical path traversal and credential-forwarding SSRF vulnerability (CWE-22) in the HTTP tool URL builder of Google’s MCP Toolbox for Databases (googleapis/mcp-toolbox). All versions prior to 1.3.0 are affected. The flaw allows unauthenticated remote attackers to supply dot-segment sequences (such as ../) in path parameters, enabling requests to arbitrary endpoints on the configured target host while forwarding the toolbox’s credentials. The vulnerability carries a CVSS 4.0 base score of 9.3 (Critical). Note: Only MCP Toolbox for Databases before v1.3.0 is affected; other products are not impacted. [NIST CVE Record]

How can organizations mitigate CVE-2026-11720?

To mitigate CVE-2026-11720, organizations should immediately upgrade to MCP Toolbox for Databases v1.3.0 or later (released May 21, 2026). The fix rejects relative and URL-encoded dot segments in path parameters and enforces that resolved paths cannot escape the configured base path scope. If immediate patching is not possible, restrict network access to the MCP Toolbox HTTP endpoint and audit all HTTP-type tool definitions that expose path parameter templates. Where feasible, disable those tools until the upgrade is applied. Note: Defense in depth is recommended—ensure backend systems apply their own authorization controls independently of the path the toolbox forwards. [Vendor Fix]

What is the impact of CVE-2026-11720 if exploited?

If exploited, CVE-2026-11720 allows an unauthenticated remote attacker to coerce the MCP Toolbox into making HTTP requests to attacker-chosen endpoints on the configured target host, forwarding the toolbox’s credentials (such as API keys, bearer tokens, or IAM identities). This exposes sensitive backend resources, including administrative APIs or secret stores. Both confidentiality and integrity are rated High in the CVSS 4.0 vector. Note: The vulnerability does not require authentication, privileges, or user interaction to trigger. [CVEProject Record]

Summary

CVE-2026-11720 is a critical path traversal vulnerability (CWE-22) in the HTTP tool URL builder of Google’s MCP Toolbox for Databases (googleapis/mcp-toolbox), carrying a CVSS 4.0 score of 9.3 (Critical). The flaw allows an unauthenticated remote attacker to supply dot-segment sequences (../) in path parameters that are silently normalized by Go’s ResolveReference during URL construction, enabling the attacker to coerce the toolbox into making requests to arbitrary endpoints on the configured target host while forwarding the toolbox’s own credentials. All versions of MCP Toolbox for Databases prior to 1.3.0 are affected; a fix was released on May 21, 2026.

Technical details

  • Root cause: When constructing downstream API requests, the HTTP tool URL builder substitutes user-controlled pathParams into the operator-configured tool path and parses the result as a relative URL. The code validates that user input does not change the scheme, host, or user-info components, but delegates final URL resolution to Go’s net/url.ResolveReference. Because ResolveReference normalizes dot segments (../, %2e%2e/) during resolution, this validation check is silently bypassed.
  • Trigger conditions: Any HTTP-type tool that exposes a path parameter template (e.g., /api/v1/users/{{.id}}) can be targeted. No authentication, privileges, or user interaction are required to trigger the vulnerability (CVSS 4.0: PR:N, UI:N).
  • Attack vector: Network (AV:N). An attacker sends a crafted MCP tool call containing path traversal sequences (e.g., ../../admin/secrets) in a path parameter. The toolbox resolves the path and issues an HTTP request to the traversed endpoint on the same configured target host.
  • Impact: The toolbox forwards its configured credentials (e.g., API keys, bearer tokens, IAM identities) to the attacker-chosen endpoint, exposing sensitive backend resources such as administrative APIs or secret stores. Both confidentiality and integrity are rated High (VC:H, VI:H) in the CVSS 4.0 vector.

Affected software

  • Google MCP Toolbox for Databases (googleapis/mcp-toolbox) — all versions before 1.3.0

Severity

  • CVSS 4.0 Base Score: 9.3 (Critical)
  • Vector String: 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

Mitigation and recommended actions

  • Immediate action — upgrade: Update to MCP Toolbox for Databases v1.3.0 or later (released May 21, 2026). The fix, introduced in PR #3218, rejects relative and URL-encoded dot segments (.., %2e%2e) in path parameters and enforces that resolved paths cannot escape the configured base path scope. It also introduces PathEscape and QueryEscape template functions for additional input hardening.
  • If immediate patching is not possible: Restrict network access to the MCP Toolbox HTTP endpoint so it is not reachable from untrusted networks. Audit all HTTP-type tool definitions that expose path parameter templates and, where feasible, disable those tools until the upgrade can be applied.
  • Defense in depth: Ensure that backend systems receiving requests from the toolbox apply their own authorization controls independently of the path the toolbox forwards, limiting the blast radius if a traversal attempt succeeds.

IONIX Status

The IONIX research team is tracking ongoing exploitation attempts and recommends immediate patching. Potentially affected assets are outlined in this post.

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.
