The LearnDash LMS – Reports plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on several functions (i.e. wrld_set_configuration, wrld_exclude_settings_save, apply_time_tracking_settings, wp_ajax_wrld_gutenberg_block_visit, etc..) in all versions up to, and including, 1.8.2.1. This makes it possible for authenticated attackers, with subscriber-level access and above, to update various plugin settings.
