| CVE-2026-45369 | Hig | 0.54 | 8.3 | 0.00 | May 14, 2026 | python-utcp is the python implementation of UTCP. Prior to 1.1.3, the _substitute_utcp_args method in cli_communication_protocol.py inserts user-controlled tool_args values directly into shell command strings without any sanitization or escaping. These commands are then executed… | ||
| CVE-2026-45370 | Hig | 0.50 | 7.7 | 0.00 | May 14, 2026 | python-utcp is the python implementation of UTCP. Prior to 1.1.3, _prepare_environment() in cli_communication_protocol.py passes a full copy of os.environ to every CLI subprocess. When combined with CVE-2026-45369, an attacker can exfiltrate all process-level secrets in a single… | ||
| CVE-2025-14542 | Hig | 0.42 | 7.5 | 0.00 | Dec 13, 2025 | The vulnerability arises when a client fetches a tools’ JSON specification, known as a Manual, from a remote Manual Endpoint. While a provider may initially serve a benign manual (e.g., one defining an HTTP tool call), earning the clients’ trust, a malicious provider can… | ||
| CVE-2026-12210 | Med | 0.41 | 6.3 | 0.00 | Jun 15, 2026 | A vulnerability was detected in universal-tool-calling-protocol python-utcp 1.1.0. This affects an unknown function of the component utcp-gql/utcp-websocket. Performing a manipulation results in server-side request forgery. The attack can be initiated remotely. The exploit is… | ||
| CVE-2026-44661 | Med | 0.31 | 4.7 | 0.00 | May 14, 2026 | python-utcp is the python implementation of UTCP. Prior to 1.1.3, the utcp-http plugin is vulnerable to a blind Server-Side Request Forgery (SSRF) caused by a trust-boundary inconsistency between manual discovery and tool invocation. register_manual() validates the discovery URL… |
