The ElementsReady Addons for Elementor plugin suffers from a stored XSS vulnerability due to improper neutralization of input during web page generation. Specifically, the '_id' parameter is not properly sanitized or escaped, allowing authenticated users with Contributor or higher privileges to inject malicious scripts. These scripts execute in the context of any user who views the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all plugin versions up to 6.1.0 and 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).

An attacker with Contributor-level or higher access can exploit this vulnerability to inject persistent malicious scripts into pages generated by the plugin. These scripts execute in the browsers of users who visit the infected pages, potentially compromising user data confidentiality and integrity. The vulnerability does not impact 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 disabling or removing the ElementsReady Addons for Elementor plugin if possible. Monitor for updates from the vendor and apply patches promptly once available.
