Vulnerability Overview

The Embed Privacy plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'embed_privacy_opt_out ' shortcode in all versions up to, and including, 1.8.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE-2023-51694 appears to be a duplicate of this vulnerability.

Technical Analysis

REMEDIATION: Update to version 1.8.1, 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.
