The The kk Star Ratings - Rate Post & Collect User Feedbacks plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 5.4.10.3. This is due to the software allowing users to execute an action that does not properly validate the 'payload' value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.
AnalysisAI
Unauthenticated shortcode injection in the kk Star Ratings - Rate Post & Collect User Feedbacks WordPress plugin (all versions through 5.4.10.3) allows any remote, unauthenticated attacker to execute arbitrary WordPress shortcodes by supplying a crafted payload to the plugin's AJAX handler. The flaw exists because the wp_ajax_kk-star-ratings action passes a user-controlled 'payload' parameter directly to do_shortcode() without allowlisting or sanitizing which shortcode tags are permitted. …
