Easy Social Feed – Social Photos Gallery – Post Feed – Like Box < 6.6.8 - Authenticated (Contributor+) DOM-Based Stored Cross-Site Scripting

Description

The Easy Social Feed – Social Photos Gallery – Post Feed – Like Box plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `data-caption` and `data-linktext` parameters in all versions up to, and including, 6.6.7 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.
