What is CVE-2026-101061?
CVE-2026-101061 is a low-severity server-side request forgery vulnerability in universal-tool-calling-protocol python-utcp, published on 27 Sep 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
utcp-gql before 1.1.1 and utcp-websocket before 1.1.1 contain server-side request forgery vulnerabilities due to incomplete application of CVE-2026-44661 fixes. The GraphQL plugin uses a vulnerable prefix check allowing bypass URLs like http://127.0.0.1.attacker.example, while the WebSocket plugin performs no URL validation despite documented security requirements. Attackers can force connections to internal services and cloud metadata endpoints by supplying malicious tool URLs in call templates, and receive configured API keys and OAuth tokens sent to attacker-controlled hosts.
