Stored XSS via unescaped Twitter username setting

Published Jan 16, 2024 · Updated Aug 30, 2024

Stored XSS in NerdPress Hubbub Lite before 1.32.0 allows remote authenticated users with admin rights to inject JavaScript. The Floating Sidebar's Twitter Username setting stores attacker-supplied markup without adequate sanitization and renders it without output escaping on the sidebar settings page. The issue is reachable only by administrators when unfiltered_html is disabled, including on multisite installations, and the script runs when a user opens the affected admin page.
