GenerateBlocks <= 2.2.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via Headline Block 'linkMetaFieldType' Dynamic Link Attribute
Published Jul 3, 2026

MEDIUMCVSS 3.1
EPSS 0.36%
Description
The GenerateBlocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Headline Block 'linkMetaFieldType' Dynamic Link Attribute in all versions up to, and including, 2.2.1 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. A contributor-level attacker can store a JavaScript payload in their own profile description (allowlisted by get_safe_user_meta_keys()) and prepend 'javascript:' via the linkMetaFieldType attribute, creating a fully attacker-controlled href that executes when any user, including an administrator, clicks the rendered headline link.
