Description

The Autoptimize plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 3.0.4 via the 'ao_ccss_export_callback' and 'ao_ccss_import_callback' functions. The settings.json file is not deleted in the import/export callbacks, which could lead to the settings options being leaked. This can allow unauthenticated attackers to extract sensitive data about the plugin's settings.
