WordPress Plugin Vulnerabilities

Smart Slider 3 < 3.5.1.39 - Contributor+ Stored XSS via 'data-href' Attribute in Custom HTML Block

Description

The plugin is vulnerable to Stored Cross-Site Scripting via the 'data-href' parameter due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
