CVE-2022-4971· NVD / CVE Program· CNA Wordfence

Sassy Social Share <= 3.3.3 - Reflected Cross-Site Scripting

The Sassy Social Share plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'urls' parameter called via the 'heateor_sss_sharing_count' AJAX action in versions up to, and including, 3.3.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
