Administrator-level stored XSS via unescaped settings
Published Jan 20, 2026 · Updated Jan 20, 2026
Stored XSS in Viet contact 1.3.2 and earlier allows remote authenticated users with administrator access to inject scripts through admin settings. The settings handling for the ll1, ll2, ll3, and ll4 parameters stores insufficiently sanitized input that the plugin later renders without output escaping. Exploitation requires administrator-level access and either WordPress multisite or disabled unfiltered_html; the script executes when a user visits an affected page.
