Command execution via shell-expanded skill arguments
Published May 10, 2026 · Updated May 10, 2026
OS command injection in 8421bit MiniClaw 0.8.0 and 0.9.0 allows attackers to execute commands through crafted skill arguments. The executeSkillScript method places attacker-controlled serialized arguments in a quoted command string passed to execAsync, where shell parsing expands injected metacharacters. Exploitation requires access to invoke skill execution with controlled arguments, and injected commands run with the MiniClaw process privileges.
