Command Injection

Overview utcp-cli is an UTCP communication protocol plugin for wrapping local command-line tools. Affected versions of this package are vulnerable to Command Injection via the substituteutcpargs function. An attacker can execute arbitrary shell commands by supplying crafted input to the toolargs...

Server-side Request Forgery (SSRF)

Overview @utcp/http is a HTTP utilities for UTCP Affected versions of this package are vulnerable to Server-side Request Forgery SSRF via the OpenApiConverter process. An attacker can access internal network resources and sensitive metadata endpoints by supplying a malicious OpenAPI specification...

CVE-2026-45369 python-utcp: Command Injection via Unsanitized Argument Substitution in CLI Communication Protocol

python-utcp is the python implementation of UTCP. Prior to 1.1.3, the substituteutcpargs method in clicommunicationprotocol.py inserts user-controlled toolargs values directly into shell command strings without any sanitization or escaping. These commands are then executed via /bin/bash -c Unix o...

CVE-2026-45369

Summary: CVE-2026-45369 affects python-utcp prior to 1.1.3, where _substitute_utcp_args in cli_communication_protocol.py injects user-controlled tool_args directly into shell commands without sanitization, leading to potential Remote Code Execution when commands are run via /bin/bash -c (Unix) or...

CVE-2026-45370

python-utcp is the python implementation of UTCP. Prior to 1.1.3, prepareenvironment in clicommunicationprotocol.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 tool call. This...

CVE-2026-45370 python-utcp: Full Process Environment Exposed to CLI Subprocess - Secrets Leakage via Command Injection

CVE-2026-45370

CVE-2026-45370 affects the python-utcp project. The vulnerability resides in _prepare_environment() in cli_communication_protocol.py, which before version 1.1.3 passes a full copy of os.environ to every CLI subprocess. When combined with CVE-2026-45369, this can allow an attacker to exfiltrate al...

CVE-2026-44661 python-utcp: SSRF via attacker-controlled OpenAPI servers[0].url in HTTP communication protocol

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. registermanual validates the discovery URL against an HTTPS /...

CVE-2026-44661

CVE-2026-44661 affects python-utcp (utcp-http plugin) prior to v1.1.3. The vulnerability arises because register_manual() validates discovery URLs against an HTTPS/loopback allowlist, while call_tool()/call_tool_streaming() reuse tool_call_template.url without revalidation and the OpenAPI convert...

CVE-2025-14542

The CVE-2025-14542 issue affects the Python UTCP client library (utcp) where the client trusts a tool’s JSON Manual from a remote Manual Endpoint. A malicious remote Manual can alter the specification to execute arbitrary commands on the client, enabling remote code execution. Remediation provide...

CVE-2025-14542 Command execution in python-utcp allows attackers to achieve remote code execution when fetching a remote Manual from a malicious endpoint

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 later change the manual to...
