CVE-2026-2518

The FastX theme for WordPress is vulnerable to unauthorized limited plugin installation and activation due to missing capability checks on the 'ultp_install_callback' and 'ultp_activate_callback' functions in all versions up to, and including, 1.0.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to install and activate the PostX plugin.
