A command injection vulnerability has been identified in the Oclif command-line interface (CLI) versions through 4.23.16. The issue arises in the JIT Plugin Entry Handler, where the child_process.exec function is used to execute commands. The vulnerability allows for arbitrary OS command execution by manipulating the jitPlugins argument in the project's package.json file. This exploitation requires local access and can be executed through the public Oclif CLI by running the 'oclif manifest' command with a crafted project that includes malicious JIT plugin entries.
Users can upgrade to Oclif version 4.23.20 or later, where this vulnerability has been fixed.
