CVE-2026-43992

JunoClaw is an agentic AI platform built on Juno Network. Prior to 0.x.y-security-1, every MCP write tool (send_tokens, execute_contract, instantiate_contract, upload_wasm, ibc_transfer, etc.) accepted 'mnemonic: string' as an explicit tool-call parameter. The BIP-39 seed was consequently embedded in the LLM tool-call JSON, exposing it to any transport, log, or telemetry surface in the path between the LLM provider and the MCP process. This vulnerability is fixed in 0.x.y-security-1.

Summary		(es) JunoClaw es una plataforma de IA agéntica construida sobre Juno Network. Antes de 0.x.y-security-1, cada herramienta de escritura de MCP (send_tokens, execute_contract, instantiate_contract, upload_wasm, ibc_transfer, etc.) aceptaba ’mnemonic: string’ como un parámetro explícito de llamada a herramienta. La semilla BIP-39 fue consecuentemente incrustada en el JSON de llamada a herramienta del LLM, exponiéndola a cualquier superficie de transporte, registro o telemetría en la ruta entre el proveedor del LLM y el proceso de MCP. Esta vulnerabilidad está corregida en 0.x.y-security-1.
