What is CVE-2026-93778?
CVE-2026-93778 is a high-severity cross-site scripting vulnerability in jgwhite33 WP Yelp Review Slider, published on 22 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-79
