Vulnerability Overview

The WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via a featured image 'alt' attribute in versions up to, and including, 8.1.1 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. The WooCommerce Blocks plugin for WordPress is vulnerable to the same issue in versions up to, and including, 11.1.1.

Technical Analysis

REMEDIATION: Update to version 8.2.0, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
