The ElementsReady Addons for Elementor plugin suffers from a stored cross-site scripting vulnerability due to improper neutralization of input during web page generation. Specifically, SVG file uploads are not properly sanitized or escaped, enabling authenticated users with Author-level privileges or above to inject arbitrary JavaScript code. This code executes in the context of users who view the SVG files, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all plugin versions up to 6.4.3. No vendor-provided patch or remediation guidance is currently available.

An attacker with Author-level access or higher can exploit this vulnerability to inject malicious scripts via SVG file uploads. These scripts execute in the browsers of users who access the SVG files, potentially leading to information disclosure or session compromise. The vulnerability does not impact availability and requires authenticated access, limiting the attack surface. 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 available, restrict Author-level user permissions to trusted individuals only and consider disabling SVG file uploads if possible. Monitor for updates from quomodosoft regarding patches or official mitigations.
