JunoClaw: plugin-shell shell-injection bypass via substring blocklist

Published May 12, 2026 CVSS 3.1 · 8.4 High EPSS < 1% KEV · Not listed
Description
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.
