Vulnerability Description
Syntx'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 syntax (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.
