CVE-2026-2518
No known patch is available for this vulnerability.
The affected theme has not been updated on WordPress.org since before this CVE was disclosed; the latest installable version is still vulnerable. If you have the affected software installed, you should uninstall or replace it rather than wait for an update.
Description
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.
