Authorization Bypass in Cozy Blocks WordPress Plugin

Publication date: 2026-09-01

Last updated on: 2026-09-01

Assigner: Wordfence

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.

Executive Summary

This WordPress plugin vulnerability allows unauthenticated attackers to bypass authorization checks and access sensitive WooCommerce product data that should be private. The flaw exists because the plugin emits a valid authentication nonce in public page HTML without requiring login, enabling attackers to harvest this nonce and retrieve restricted product information like names, prices, and stock status.

Detection Guidance

To detect this vulnerability, check if the Cozy Blocks plugin is installed and verify its version. If it is version 2.2.17 or lower, the system is vulnerable. Inspect WordPress pages for exposed sidebarNonce values in page HTML, which could allow unauthorized access to sensitive product data.

Impact Analysis

If you use this plugin, attackers could access confidential product details that were meant to be hidden, potentially leading to data leaks or competitive disadvantages. The vulnerability also exposes internal product management information that could be misused for targeted attacks or phishing campaigns.

Compliance Impact

This vulnerability could violate data protection regulations like GDPR by exposing personal or sensitive product data without authorization. For organizations handling protected health information, it may also conflict with HIPAA requirements for safeguarding confidential data.

Mitigation Strategies

Update the Cozy Blocks plugin to the latest version beyond 2.2.17 to patch the authorization bypass vulnerability. If an update is not available, consider disabling the plugin temporarily until a fix is released.
