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

{
    "lastseen": "",
    "description": "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 tool call. This vulnerability is fixed in 1.1.3.",
