AI Analysis
Technical Summary
CVE-2026-15336 is a missing authorization vulnerability (CWE-862) in the Catch Themes Demo Import WordPress plugin (<=3.3). The vulnerability exists in the catch_themes_demo_import_activate_plugin() function, which is triggered on admin_init when the activate_plugin GET parameter is present. This function calls Plugin_Upgrader::install() to download and install the hardcoded 'essential-content-types' plugin from WordPress.org before performing the current_user_can('activate_plugins') capability check. This sequence allows authenticated users with subscriber-level privileges or higher to install plugins without proper authorization.
Potential Impact
Authenticated users with subscriber-level access or higher can install the 'essential-content-types' plugin without proper authorization. This could lead to unauthorized plugin installation, potentially enabling further privilege escalation or other malicious activities depending on the installed plugin's capabilities. There is no direct impact on confidentiality or availability reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch is currently documented. Until a patch is available, restrict user roles to prevent untrusted users from having subscriber-level or higher access, or disable the Catch Themes Demo Import plugin if not required.
