CVE-2026-81098 — Telnyx: The Telnyx MCP server exposed its HTTP transport on every interface and did not
The Telnyx MCP server exposed its HTTP transport on every interface and did not require a caller credential. packages/mcp-server/src/http.ts served MCP on the root path with a listener bound to all interfaces and parsed the caller's authentication headers in a mode that did not fail when they were absent, so a request without any credential completed initialisation and dispatched tools. Dispatch forwarded the server's own stored credentials, the Telnyx API key and client secr CVSSv3.1 9.1 (CRITICAL)
