What it is

The WP Yelp Review Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Yelp Review Text (imported via wpyelp_download_source) in all versions up to, and including, 9.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The malicious payload originates from an anonymous Yelp reviewer on a public platform and requires no WordPress account; it is introduced into the database during the site administrator's ordinary use of the plugin's Download Reviews feature, making the effective attacker unauthenticated.
