AddThis <= 5.0.2 - Authenticated Stored Cross-Site Scripting
Strategic Overview
< 5.0.3N/AVulnerability Overview
The AddThis plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘at_async_loading’ AJAX action in versions up to, and including, 5.0.2 due to insufficient input sanitization and output escaping. This makes it possible for Subscriber-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
