CVE-2026-5934WP Rocket <= 3.21.0.1 - Unauthenticated Stored Cross-Site Scripting via Picture Source Attributes in rocket_beacon Endpoint

WP Media WP Rocket Published: 2026-08-28 14:29 (2 months ago)

Description

The WP Rocket plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.21.0.1. This is due to insufficient input sanitization and output escaping of user-supplied data via the rocket_beacon AJAX endpoint. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Weakness (CWE): CWE-79

Data: CVE.org, NVD, CISA KEV, FIRST EPSS, Ubuntu. Published as the sources state it, in English.
