Published Oct 27, 2023 · Updated Feb 5, 2025

Cross-site request forgery in I Thirteen Web Solution Responsive Thumbnail Slider 1.0 allows remote attackers to delete sliders in bulk. The deleteselected function processes destructive requests without validating a nonce, causing the administrator's authenticated session to authorize mass deletion. Exploitation requires a site administrator with an active WordPress session to follow an attacker-controlled link, and the bounded consequence is deletion of slider records.
