The 10Web Booster – Website speed optimization, Cache & Page Speed optimizer plugin for WordPress is vulnerable to arbitrary folder deletion due to insufficient file path validation in the getcachedirforpagefromurl() function in all versions up to, and including, 2.32.7. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary folders on the server, which can easily lead to a loss of data or a denial of service condition.
