3Description
Roo Code's command auto-approval module contains a critical OS command injection vulnerability that renders its whitelist security mechanism completely ineffective. The system relies on fragile regular expressions to parse command structures; while it attempts to intercept dangerous operations, it fails to account for standard Shell command substitution Roo Code (specifically$(...)and backticks ...). An attacker can construct a command such as git log --grep="$(malicious_command)", forcing Syntx to misidentify it as a safe git operation and automatically approve it. The underlying Shell prioritizes the execution of the malicious code injected within the arguments, resulting in Remote Code Execution without any user interaction.
Analysis
Remote code execution in Roo Code's command auto-approval module allows unauthenticated attackers to bypass the whitelist security mechanism via shell command substitution in command arguments. The vulnerability exploits inadequate regular expression parsing that fails to detect $(...) and backtick syntax, enabling an attacker to inject malicious commands (e.g., git log --grep="$(malicious_command)") that are automatically approved and executed with full system privileges. …
