What is CVE-2026-15336?
CVE-2026-15336 is a medium-severity missing authorization vulnerability in catchplugins Catch Themes Demo Import, published on 16 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The Catch Themes Demo Import plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 3.3. This is due to the catch_themes_demo_import_activate_plugin() function, hooked on admin_init when the activate_plugin GET parameter is present, calling Plugin_Upgrader::install() to download and install a plugin from WordPress.org before performing the current_user_can('activate_plugins') capability check. This makes it possible for authenticated attackers, with subscriber-level access and above, to install the hardcoded 'essential-content-types' plugin from the WordPress.
