Settings modification via nonce-free administrative POST
Published Apr 22, 2026 · Updated Apr 22, 2026
Cross-site request forgery in byybora Google PageRank Display 1.4 and earlier allows remote attackers to change settings via a crafted request. The gpdisplay_option() settings handler passes POST data to update_option() without a form nonce or check_admin_referer() or wp_verify_nonce() validation. Exploitation requires a logged-in administrator to submit the attacker-controlled request, and the demonstrated consequence is unauthorized modification of the badge display style.
