Description
The NitroPack plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the nitropack_set_compression_ajax() function in all versions up to, and including, 1.18.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update the nitropack-enableCompression option and effectively change plugin compression settings.
