What is CVE-2026-43992?

The JunoClaw AI platform, built on the Juno Network, suffers from a vulnerability that allows sensitive data, specifically BIP-39 seeds, to be directly exposed through tool-call parameters. Tools such as send_tokens, execute_contract, instantiate_contract, upload_wasm, and ibc_transfer, prior to version 0.x.y-security-1, transmitted the 'mnemonic: string' openly in their JSON tool-call structures. This oversight means that any transport, log, or telemetry surfaces could inadvertently store this sensitive information, placing users at risk. To safeguard against this vulnerability, users are urged to upgrade to version 0.x.y-security-1 or later.
