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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
