Description
ATXP Gemini CLI extension through 1.0.0 contains an OS command injection vulnerability in runAtxp() that allows attackers to execute shell commands through unsanitized MCP tool parameters. Attackers can plant instructions in email or SMS content to inject $() or backtick substitutions into parameters like message_id, subject, or query, running commands as the user.
