Vulnerability from github – Published: 2026-09-22 09:31 – Updated: 2026-09-22 09:31

Details

The ThumbPress plugin for WordPress is vulnerable to unauthorized access in versions up to and including 6.2.1. This is due to missing capability checks and nonce verification in the send_deactivation_survey() function registered via the wp_ajax_pl-plugin-deactivation AJAX action. This makes it possible for authenticated attackers, with Subscriber-level access and above, to deactivate the ThumbPress plugin on the affected site by sending a crafted POST request to admin-ajax.

Severity

4.3 (Medium)
