WordPress Infinite Scroll – Ajax Load More < 7.4.1 - Authenticated(Contributor+) Stored Cross-Site Scripting

Description

The WordPress Infinite Scroll – Ajax Load More plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the data-button-label HTML attribute in all versions up to, and including, 7.4.0.1 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.
