CVE-2026-14625Public exploitNetwork attack vector

Authenticated command execution via omitted Tirith scanning

Published Jul 4, 2026 · Updated Jul 4, 2026

Command-execution guard bypass in Hermes Agent 0.15.0 through 0.15.2 allows remote authenticated users to execute shell commands. The shell.exec JSON-RPC handler applies only detect_dangerous_command(), while Quick Command paths launch shells without check_all_command_guards() or the Tirith scanner. Access to the TUI JSON-RPC interface or a configured Quick Command is required; successful exploitation runs commands with Hermes Agent daemon privileges.
