CVE-2025-8605 is a stored cross-site scripting vulnerability in the Gutenify – Visual Site Builder Blocks & Site Templates WordPress plugin. It affects all versions up to 1.5.9 due to improper neutralization of input during web page generation (CWE-79). Authenticated users with contributor or higher privileges can inject arbitrary JavaScript via block attributes that are not properly sanitized or escaped. This injected script executes in the context of any user viewing the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and partial impact on confidentiality and integrity without affecting availability.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via block attributes. These scripts execute in the browsers of users who view the infected pages, potentially exposing sensitive information or enabling further attacks such as session hijacking. The vulnerability impacts confidentiality and integrity but does not affect availability. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider removing or disabling the Gutenify plugin if possible. Monitor for updates from the vendor and apply patches promptly once available.
