What is CVE-2026-13015?
CVE-2026-13015 is a medium-severity cross-site scripting vulnerability in jgwhite33 WP Google Review Slider, published on 1 Jul 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
The Wp Google Places Review Slider plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'place' parameter in versions up to, and including, 18.1. This is due to insufficient input sanitization and output escaping in admin/partials/googlecrawl_dfs.php, where the $_GET['place'] value is URL-decoded, stripslashes()'d, and echoed directly into an HTML value attribute with no esc_attr() call when the supplied place is not already a stored key in the wprev_google_crawls option. 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 specially crafted link.
