import-in-the-middle is a module loading interceptor specifically for ESM modules. The import-in-the-middle loader works by generating a wrapper module on the fly. The wrapper uses the module specifier to load the original module and add some wrapping code. Prior to version 1.4.2, it allows for remote code execution in cases where an application passes user-supplied input directly to the import()
function. This vulnerability has been patched in import-in-the-middle version 1.4.2.
Some workarounds are available. Do not pass any user-supplied input to import()
. Instead, verify it against a set of allowed values. If using import-in-the-middle, directly or indirectly, and support for EcmaScript Modules is not needed, ensure that no options are set, either via command-line or the NODE_OPTIONS
environment variable, that would enable loader hooks.
