CVE-2025-4420 Information

Description

The Vayu Blocks – Gutenberg Blocks for WordPress & WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘containerWidth’ parameter in all versions up to and including 1.3.1 due to a missing capability check on the vayu_blocks_option_panel_callback() function and insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with Subscriber-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
