CVE-2026-43990 Details
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.
A shell-metacharacter injection vulnerability has been identified in the JunoClaw AI platform, specifically within the plugin-shell component, in versions prior to v0.x.y-security-1. The issue arises because the run_command function wrapped agent-supplied commands in a shell command execution wrapper, passing the entire argument string to the shell's parser. This allowed shell metacharacters in agent-provided arguments to be interpreted as command syntax, creating a potential for injection attacks.
Users can upgrade to JunoClaw version v0.x.y-security-1 or later to address this vulnerability. Instructions for upgrading are available in the JunoClaw repository's release notes.
