Cozy Blocks exposes unpublished WooCommerce product data

Cozy Blocks through 2.2.17 emits sidebarNonce on public pages and accepts it as the only authorization check in the affected handler. An unauthenticated visitor can use that nonce to retrieve names, prices, short descriptions, image URLs, permalinks, stock status, and product types for draft, pending, private, or catalog-hidden WooCommerce products.

What to do

Update, patch or deactivate.

Update Cozy Blocks to 2.2.18 or later and assess whether unpublished or hidden product information was exposed.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical description

The Cozy Blocks – Page Builder for Gutenberg Editor & FSE with 700+ Patterns, 58 Blocks & Templates plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.2.17. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to retrieve the name, price, short description, image URL, permalink, stock status, and product type of draft, pending, private, and catalog-hidden WooCommerce products not intended to be publicly visible. The sidebarNonce value is emitted unconditionally into public page HTML by multiple block renderers with no login gate, allowing unauthenticated visitors to harvest a valid nonce and pass the only authentication check in the handler.
