Plugin slug: catch-themes-demo-import
Affected: <= 3.3
Safe version: See mitigation notes
Published: Jul 16, 2026
Weakness: CWE-862 — Missing Authorization

This CVE was published Jul 16, 2026 and is one of 3 known issues for this plugin.

What to do

Update, patch or deactivate.

No fixed release is identified. Update Catch Themes Demo Import when a release after 3.3 becomes available; until then, disable and remove it when the site's risk warrants. The official upstream changelog lists version 3.4, which is newer than the published affected range. Its changelog does not clearly confirm this specific fix, so it is not counted as a known-safe release.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical 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.
