CVE-2021-24300Public exploitNetwork attack vector

Browser script execution via unsanitized search keyword

Published May 24, 2021 · Updated Aug 3, 2024

Reflected XSS in PickPlugins Product Slider for WooCommerce before 1.13.22 allows remote attackers to execute script via a crafted keyword. The slider import search in the plugin settings returns the keyword GET parameter in the page without proper sanitization, allowing injected event-handler markup to execute. Exploitation requires a user with access to the plugin's wp-admin import page to open the crafted URL, exposing that browser session to script execution.
