DescriptionNVD

JunoClaw is an agentic AI platform built on Juno Network. Prior to 0.x.y-security-1, plugin-shell's run_command wrapped every agent-supplied command in 'sh -c' / 'cmd /C' and passed the full argument string to the shell's parser, allowing shell metacharacters in agent-supplied arguments to be interpreted as command syntax. This vulnerability is fixed in 0.x.y-security-1.

AnalysisAI

Command injection in JunoClaw agentic AI platform versions prior to 0.x.y-security-1 allows local attackers to execute arbitrary shell commands with high integrity and confidentiality impact. The plugin-shell component wrapped agent-supplied commands in 'sh -c' or 'cmd /C' without sanitizing shell metacharacters, enabling malicious AI agents or compromised agent inputs to break out of intended command boundaries. …
