Name of the Vulnerable Software and Affected Versions Flatsome theme for WordPress versions up to, and including, 3.18.7

Description The issue is related to Stored Cross-Site Scripting via the plugin's shortcode(s) due to insufficient input sanitization and output escaping on user-supplied attributes. This allows 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.

Recommendations For versions up to, and including, 3.18.7, update to a version that includes the necessary security patches to address the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the plugin's shortcode(s) to minimize the risk of exploitation.
