Fixed in: 2.2.28 *
Access needed (per CVSS): Needs a low-level account (e.g. subscriber)
Range from: CVE record (the advisory publisher) · score by Wordfence

Details from the advisory

The Cozy Blocks – Website Builder for WordPress Block Editor | Gutenberg Blocks, Patterns & Templates plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'content (block attribute icon.view / icon.layout / icon.gap)' parameter in all versions up to, and including, 2.2.27 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. Although wp_kses_post is applied on save, it does not neutralize a quote-only attribute-breakout payload containing no '<' character, leaving the block comment and its decoded JSON attributes intact and exploitable at render time.

Missing authorization check in Cozy Blocks (2.2.17 and older)

Affected: 2.2.17 and older
Fixed in: 2.2.18 *
Access needed (per CVSS): No login needed
Range from: CVE record (the advisory publisher) · score by Wordfence

Details from the advisory

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.

Fixed in: 2.2.17 *
Access needed (per CVSS): Needs a low-level account (e.g. subscriber)
Range from: CVE record (the advisory publisher) · score by Wordfence

Details from the advisory

The Cozy Blocks – Page Builder for Gutenberg Editor & FSE with 700+ Patterns, 58 Blocks & Templates plugin for WordPress is vulnerable to Stored Cross-Site Scripting via cozyHoverEffect Block Attribute in all versions up to, and including, 2.2.16 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 payload survives wp_kses_post on save because it contains no angle brackets — only a double-quote breakout of the cozyHoverEffect.boxShadow.color attribute value — allowing event-handler injection at the render stage.
