GeneratePress vulnerabilities and threats

CVE-2026-121773 is a stored cross-site scripting (XSS) vulnerability in GenerateBlocks, a plugin for GeneratePress. The flaw allows improper neutralization of input during web page generation, potentially enabling attackers with limited privileges to inject malicious scripts. This vulnerability affects GenerateBlocks versions from initial releases up to 2.5.0. A fix is available in version 2.5.1.

The GP Premium plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the message parameter in all versions up to, and including, 2.4.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
