CVE-2026-110206 · Severity: high · CVSS 8.8 · Published 2026-10-13

Roo Code is an AI coding assistant that automatically approves and executes shell commands when the "always approve" setting is enabled. An attacker can bypass the approval allowlist by wrapping a malicious command in shell command substitution syntax (such as $(echo malicious_command)), causing the system to approve the inner harmless command but execute the malicious output instead, achieving arbitrary command execution on the developer's machine.

## Technical details

The vulnerability is a logic error in the command approval parser (parseCommandLine() and getCommandDecision()): when a command substitution like $(echo touch /tmp/x) appears at command position, the approval check extracts and validates only the inner command (echo touch /tmp/x), which matches the echo allowlist. However, bash executes the substitution by first running the inner command and then executing its standard output as a new command, so the attacker's touch /tmp/x is executed without approval. This represents a fundamental gap in the approval model's understanding of shell semantics. The vulnerability requires that "always approve execute" be enabled and that the attacker can inject commands into the agent's prompt (indirect prompt injection).
