AI Analysis
Technical Summary
The Plus Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability due to improper neutralization of input in the 'xai_username' parameter. Authenticated users with contributor or higher privileges can inject arbitrary web scripts that persist and execute in the context of other users viewing the affected pages. This vulnerability is tracked as CVE-2024-4484 and has a CVSS 3.1 base score of 6.4 (medium severity). No vendor advisory or patch links are currently available, and the plugin is not a cloud service, so remediation depends on the vendor releasing an update.
Potential Impact
An attacker with contributor-level or higher permissions can inject persistent malicious scripts into pages via the vulnerable parameter. This can lead to the execution of arbitrary scripts in the context of users visiting those pages, potentially resulting in session hijacking, privilege escalation, or other client-side impacts. The vulnerability does not affect availability and requires authenticated access, limiting its scope to users with some level of trust on the site.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level permissions carefully and monitor for suspicious activity related to page content modifications. Avoid granting contributor or higher privileges to untrusted users. Follow updates from the plugin vendor for a security patch addressing this vulnerability.
