The WP-Optimize – Cache, Compress images, Minify & Clean database to boost page speed & performance plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the unscheduled_original_file_deletion function in all versions up to, and including, 4.5.2 This makes it possible for authenticated attackers, with author-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This is possible because 'original-file' is a public (non-protected) meta key — it does not begin with an underscore — allowing Authors to freely create or modify it on their own attachment posts via the standard Edit Media form or the REST API.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
