CVE-2026-15336Network attack vector

Subscriber-level plugin installation via late capability check

Published Jul 16, 2026 · Updated Jul 16, 2026

Missing authorization in Catch Plugins Catch Themes Demo Import 3.3 and earlier allows remote authenticated users to install a WordPress plugin. The catch_themes_demo_import_activate_plugin() admin_init handler invokes Plugin_Upgrader::install() for the hardcoded essential-content-types package before checking the activate_plugins capability. Subscriber-level access and an activate_plugin GET parameter are sufficient; the bounded consequence is installation of that single plugin.
