CVE-2026-43991: DRAGONMONK111 Junoclaw

High severity, CVSS 8.4. EPSS: 0.3% 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, substring-based blocklist in plugin-shell's command-safety check could be bypassed by adversarial argument constructions, allowing unauthorized command execution on the host when combined with the companion advisory. Pre-patch, the check was applied to the raw command string rather than the parsed first token. This vulnerability is fixed in 0.x.y-security-1.
