Vulnerability Title
JunoClaw: plugin-shell shell-metacharacter injection via shell wrapper
Source: NVD (National Vulnerability Database)
Vulnerability Description
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.
