 "title": "Uncanny Toolkit for LearnDash <= 3.8.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via uo_login Shortcode Label Attributes",
 "description": "The Uncanny Toolkit for LearnDash plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'username-label' and 'password-label' attributes of the [uo_login] shortcode in all versions up to, and including, 3.8.2. This is due to the plugin echoing these values without escaping inside a single-quoted JavaScript string in an inline script. This makes it possible for authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages. The scripts run whenever a logged-out visitor opens an injected page.",
