CVE-2024-4440 is a stored cross-site scripting vulnerability in the Xpro Addons — 140+ Widgets for Elementor WordPress plugin, affecting all versions up to 1.4.3. The vulnerability is due to insufficient input sanitization and output escaping on user-supplied attributes within the plugin's widgets. This allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts that execute in the context of users viewing the compromised pages. The CVSS 3.1 base score is 6.4, reflecting a medium severity with network attack vector, low attack complexity, and privileges required at the contributor level.

Successful exploitation allows an authenticated contributor or higher to inject persistent malicious scripts into pages, which execute when other users access those pages. This can lead to limited confidentiality and integrity impacts, such as theft of user session data or manipulation of page content. There is no impact on availability. No known exploits in the wild have been reported.

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 vulnerable widgets. Monitor vendor communications for updates on patches or official mitigations.
