Vulnerability from github – Published: 2026-07-29 03:30 – Updated: 2026-07-29 03:30

Details

The WowStore – Store Builder & Product Blocks for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'filterMobileText' Block Attribute in all versions up to, and including, 4.4.24 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 save-time wp_kses_post sanitization is ineffective because the payload is stored inside a Gutenberg block delimiter comment as JSON, which wp_kses_post preserves, allowing an attribute-breakout string to survive to the server-side render_callback.

Severity

6.4 (Medium)
