Authenticated stored XSS via unescaped page content
Published Apr 1, 2025 · Updated Apr 28, 2026
Stored XSS in Yazamo LeadQuizzes 1.1.0 and earlier allows remote authenticated users to inject scripts into WordPress pages. The plugin accepts contributor-controlled page content without sufficient input sanitization and later renders it without adequate output escaping. Contributor-level access is required, and the script executes when another user opens the injected page, exposing that user's browser session to attacker-controlled actions.
