Administrator-level stored XSS via unescaped preset setting
Published Feb 28, 2022 · Updated Aug 3, 2024
Stored XSS in Max Foundry WP-Paginate before 2.1.4 allows remote authenticated users to run script in a victim's browser. The settings handler stores the preset parameter without sanitizing it or escaping it when the settings page renders, turning supplied markup into executable content. An administrator-level WordPress account and a subsequent visit to the affected settings page are required; execution remains in the visiting user's browser context.
