Last modified

CVE-2021-24331 is a medium-severity vulnerability rated 4.8/10 on the CVSS scale. The Smooth Scroll Page Up/Down Buttons WordPress plugin before 1.4 did not properly sanitise and validate its settings, such as psb_distance, psb_buttonsize, psb_speed, only validating them client side. This could allow high privilege users (such as admin) to set XSS payloads in them. EPSS estimates a 0.65% chance of exploitation in the next 30 days.
