DescriptionNVD

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.

AnalysisAI

Command injection in JunoClaw's plugin-shell allowed adversarial argument construction to bypass the substring-based blocklist and achieve unauthorized command execution on the host when the unsafe-shell feature was enabled. Attackers could craft commands with special tokens or argument patterns to evade blocklist checks that scanned raw command strings instead of parsed first tokens. …
