CVE-2024-1940 describes a stored cross-site scripting vulnerability in the Brizy – Page Builder WordPress plugin (versions ≤ 2.4.41). The flaw results from improper neutralization of input during web page generation (CWE-79), specifically due to input sanitization only on the client side and insufficient output escaping on the server side. This allows authenticated users with contributor or higher privileges to embed malicious scripts into post content, which execute in the context of any user viewing the compromised page. The vulnerability is network exploitable with low attack complexity and no user interaction required beyond viewing the page.

Successful exploitation allows an authenticated contributor or higher to inject malicious scripts that execute in the browsers of users who visit the compromised pages. This can lead to unauthorized actions performed on behalf of users, potentially compromising user sessions or integrity of displayed content. The vulnerability does not impact confidentiality but has high impact on integrity and low impact on availability as per the CVSS vector.

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 the use of the Brizy – Page Builder plugin. Monitor for updates from the vendor and apply patches promptly once available.
