CVE-2026-81098 – Missing Authentication / Credential Exposure – Telnyx MCP Server (telnyx-mcp) ≤ 6.8

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

Summary

CVE-2026-81098 is a critical missing-authentication vulnerability (CWE-306) in the Telnyx MCP Server (telnyx-mcp npm package), affecting all versions through 6.83.0. The server’s Streamable HTTP transport listened on all network interfaces and accepted tool-dispatch requests even when no authentication header was supplied, allowing an unauthenticated network attacker to invoke server tools that acted using the server’s own stored Telnyx API key and client secret. The flaw has a CVSS v3.1 base score of 9.1 (v4.0: 9.3), rated Critical.

Technical details

  • Root cause: packages/mcp-server/src/http.ts bound the HTTP listener to all interfaces (0.0.0.0) by default and parsed caller authentication headers in a mode that did not fail/reject when the headers were absent.
  • Trigger conditions: A request reaching the exposed MCP HTTP endpoint with no credential still completed session initialization and was permitted to dispatch tool calls.
  • Attack vector: Network — no authentication, no user interaction, and low attack complexity are required (AV:N/AC:L/PR:N/UI:N).
  • Impact: Tool dispatch forwarded the server’s own stored secrets — the Telnyx API key, client secret, and the code-execution key — to the upstream Telnyx endpoint on behalf of the unauthenticated caller. This gives an attacker who can reach the exposed port the ability to act with the full privileges of the server’s Telnyx account (high confidentiality and integrity impact; no availability impact per the CVSS vector).

Affected software

  • Product: Telnyx MCP Server (telnyx-mcp, npm package, part of team-telnyx/telnyx-node)
  • Versions: All versions from 0 up to and including 6.83.0
  • Fixed in: Versions after 6.83.0 (the current code defaults the host to loopback, requires a server API key, and enforces it in middleware)

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 Base 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

Mitigation and recommended actions

  • Immediate: Upgrade telnyx-mcp to a version newer than 6.83.0, which binds the HTTP listener to loopback by default, requires a server API key, and enforces authentication in middleware.
  • If unable to patch immediately:
    • Ensure the MCP server’s HTTP interface is bound to localhost/loopback rather than exposed on all network interfaces.
    • Restrict network access to the MCP server port using firewall rules or network segmentation so it is not reachable from untrusted networks or the public internet.
    • Rotate the Telnyx API key, client secret, and any code-execution keys configured on the affected server, since any exposed instance should be considered potentially compromised.
    • Audit logs for unexpected/unauthenticated tool-dispatch requests to the MCP HTTP endpoint prior to patching.

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.
