The Build Your Dream Website Fast with 400+ Starter Templates and Landing Pages, No Coding Needed, One-Click Import for Elementor & Gutenberg Blocks! – TemplateSpare plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'templatespare_activate_required_theme' and 'templatespare_get_theme_status' functions in all versions up to, and including, 2.4.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to activate any installed theme and read any theme status. If the attacker attempts to activate a theme that is not installed, a non-existent theme with the slug chosen by the attacker will be considered the active theme, leaving the site with no theme functionality.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
