Technical details
A code injection vulnerability exists in the Telegram-to-AI Tool Execution Flow of zevorn rt-claw. The root cause is the lack of an approval mechanism or 'deny-by-default' policy in the tool dispatch loop within `claw/services/tools/script.c`. When a remote Telegram user sends a message that causes the AI model to return a `run_script` tool call, the `tool_run_script_execute` function immediately executes the provided Python code via the Linux platform backend. An attacker can exploit this by influencing the AI model to trigger the `run_script` tool, resulting in arbitrary code execution with the privileges of the rt-claw process. As of the advisory date, the project has not responded to the issue report.
