The WP Hait Post Grid Elementor Addon contains a stored XSS vulnerability (CWE-79) due to improper input neutralization during web page generation. This allows an attacker with low privileges to inject malicious scripts that execute in the context of other users, potentially leading to confidentiality, integrity, and availability impacts. The vulnerability affects versions up to 2.0.16. The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, and scope changed, with low impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of other users, potentially leading to information disclosure, modification of content, or disruption of service. The impact is rated as medium severity based on the CVSS score of 6.5. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider limiting privileges of users who can input content and apply web application firewall (WAF) rules to detect and block XSS payloads. Monitor vendor channels for updates and apply patches promptly once available.
