Stored XSS via unescaped Font Family setting

Published Feb 12, 2024 · Updated Aug 2, 2024

Stored XSS in the chartjs WordPress plugin through 2023.2 allows remote authenticated users to inject script through chart settings. The Charts > Settings handler stores the Font Family value without sanitizing it or escaping it when embedded in a page script. An Administrator-level account without unfiltered_html, as in WordPress multisite, can persist JavaScript that runs when visitors load any site page.
