CVE-2026-16204Public exploitNetwork attack vector

Remote Python execution via implicit tool approval

Published Jul 19, 2026 · Updated Jul 19, 2026

Code injection in RT-Claw unreleased main after 0.2.0 allows remote attackers to execute Python through Telegram-originated AI tool calls. The AI dispatch loops call claw_tool_invoke without an approval gate, and the Linux run_script backend writes attacker-influenced code to a temporary file and starts it with python3. Exploitation requires Telegram and run_script to be enabled and the model to return the tool call; code runs with the rtclaw process privileges.
