CVE-2025-4217 Information

Description

The WP YouTube Video Optimizer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin’s ‘ib_youtube’ shortcode in all versions up to and including 1.2 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
