CVE-2026-43992: DRAGONMONK111 Junoclaw

Critical severity, CVSS 9.8. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• DRAGONMONK111 Junoclaw: before v0.x.y-security-1 (fixed in v0.x.y-security-1)
