Smart Slider 3 <= 3.5.1.38 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'data-href' Attribute in Custom HTML Block

Type: advisorySource: Official CVE List1 source record

The Smart Slider 3 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'data-href' parameter in all versions up to, and including, 3.5.1.38 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.
