The Blocksy theme for WordPress is vulnerable to unauthorized access due to a missing capability check on the wp_ajax_blocksy_notice_button_click AJAX endpoint in versions up to, and including, 2.0.97. This makes it possible for authenticated attackers, with administrator-level access and above, to install plugins.
This would only impact sites where administrators have been stripped of their capability to install and activate plugins, which might occur on multi-sites.
Not sure which version you run? Run a passive check — it reads public files only.
Remediation & mitigations
- Update to version 2.0.98, or a newer patched version
- Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
