CVE-2024-1296 is a stored cross-site scripting vulnerability (CWE-79) in the themefusecom Brizy – Page Builder WordPress plugin. It affects all versions up to 2.4.40 due to improper neutralization of input during web page generation, specifically in the block upload functionality. Authenticated users with contributor or higher privileges can inject malicious scripts that execute in the context of other users viewing the affected pages. The vulnerability has a CVSS score of 6.4 (medium severity) with network attack vector, low attack complexity, and no user interaction required. No patch or vendor advisory is currently provided.

An attacker with contributor-level or higher permissions can exploit this vulnerability to inject and store malicious scripts within pages created by the plugin. These scripts execute in the browsers of users who view the compromised pages, potentially leading to information disclosure or session hijacking limited to the scope of the injected script. The vulnerability does not affect availability and requires authenticated access.

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 disabling or limiting use of the block upload feature in the Brizy – Page Builder plugin. Monitor for updates from the vendor or WordPress plugin repository for a security patch.
